It would be better if you avoided discussing love with your cousin, which may lead to marriage at this stage. It is prohibited in many places for two persons who are first cousins or first cousins once removed to marry. Some states are much tighter, while others are more forgiving. For example, in Virginia first cousins cannot marry, but fourth cousins can. Generally, if there is any chance that you could be related to each other beyond first cousin, it's best to avoid mentioning love.
However, if you must say you love someone and you're not married to them, then saying it out loud to someone who is not related to you by blood is allowed. Your cousin should not take it as a sign of your feelings for him or her being reciprocated, though.
The only person who can truly reply "I love you" back is your spouse, so if you want to tell a cousin you love him/her, be sure to do so only to someone who is not able to respond.
It is quite OK to fall in love with a cousin and pursue marriage. However, studies reveal that children born from cousin marriages may have anomalies, but only if the marriages are inter-related. For example, if you marry your first cousin, the children of this marriage can have problems due to genetic defects. But if you marry someone who is second degree related to you, such as an aunt or uncle, there is no risk of having a disabled child.
In most countries, marrying within the same blood group is very risky because of the high probability of receiving an antigen-deficient red cell when you need one of those antigens to survive. For example, people of Group O cannot marry someone of the same group; they would both be killed by each other's blood. People of Group A must never marry anyone else but someone like themself; otherwise, their children could get hemolytic anemia, which leads to destruction of the red cells.
In general, it is not recommended to marry someone you know only through family connections because there's a high chance that you won't understand each other's minds and feelings. It's best to learn about someone before you decide to put a ring on their finger.
There is nothing wrong with falling in love with your second cousin, and unless there is a severe hereditary flaw in your family line, marriage will most likely be unaffected. The odds of your children being born with the same genetic defects are extremely low, so you should not worry about ruining their lives this way.
In some countries, first cousins marry, so you would be well advised to do some research into the law where you live before committing yourself to a long-term relationship. If you are not sure what legal restrictions may exist where you live, then you should consider waiting until you have confirmation on that matter before making any important decisions.
It is normal to feel some sort of attraction towards someone who is closely related to you. It is also natural to want to spend more time with these people, especially if they are friends and relatives you see often. In fact, studies have shown that people who have many close friends, even if some of them are not blood relatives, are healthier and live longer than those who are alone or have few friends.
Being in love with your second cousin is not going to harm anyone else, so you have no reason to hide this part of your life from others. You should not feel guilty for feeling this way because it is normal to feel some type of connection with everyone living on earth.
There is nothing wrong with having feelings for a cousin. Cousin marriage is banned in most countries and remains a taboo, yet being in love is all about shattering taboos and preconceptions. However, you should be informed that cousin weddings may result in defects in the children.
Please don't tell her. For starters, marrying a cousin is generally regarded a negative decision since inbreeding can result in severe genetic disorders. First cousins are somewhat more likely to produce a kid with a significant birth defect, mental retardation, or genetic illness than unrelated parents.
If you fall in love with a cousin, do not be afraid to talk about it because it is frowned upon. People who have fallen in love with and subsequently married their cousins frequently comment that marrying a cousin is similar to marrying a friend. They say that since they have no reason to suspect your marriage of being anything other than what it appears to be, there is no reason for them to object to it.
In some cases, a distant relative may develop feelings for someone close to their family. If the two people involved are willing to consider the consequences, marry while you can find out how far these feelings go. It may not be as bad as you think if one day you discover that you are both related somehow.
Marriage between cousins should never be assumed to be legitimate or lawful. Such marriages were common in the past but today they are considered incestuous by most people. The only way to know for sure whether you are married to your cousin is to search through old records or ask relatives if they know of any marriages between the two of you. If you find out later that you are not legally married, then you will need to get a divorce so that you do not violate any laws against adultery.
In some states, being married to your cousin can also lead to other problems such as inheriting property together or having children together.
Marriage to a cousin who is your second cousin or farther is lawful in all 50 states. Third and fourth cousin weddings are the "best of both worlds," as the saying goes. They're dinnertime breakfast foods. You escape the inbreeding hazards associated with closer relatives, yet your genes are near enough that they naturally complement each other. In fact, scientists have shown that individuals who are third cousins or greater are likely to possess identical-by-descent (IBD) alleles — genetic markers — at many loci across their genomes.
The only real drawback to marrying a third cousin is that if you have children by this marriage, they have a 1 in 4 chance of being born with severe birth defects. But since most third-cousin marriages don't produce children, this problem isn't very common. The disorder rate for children born to married parents is about the same as for those born to non-married parents.
You can marry your third cousin once either before or after both of them marry someone else. If you do so before they marry then they cannot marry another third cousin; instead, they must marry someone not related to them by blood or marriage on one side and married to someone not their own blood relative on the other. If you do so after they've married then they can marry another third cousin provided they divorce the first spouse first.
People tend to think that only close relatives can marry each other, but this is not true.
They claim that there is no biological basis to prevent cousins from marrying. According to the researchers, first cousins are somewhat more likely than unrelated parents to have a kid with a significant birth defect, mental retardation, or genetic illness, but their elevated risk is nowhere like as great as most people believe. Is marrying your cousin a sin? This depends on what you call a sin. If you believe that marriage is only between one man and one woman, then yes, marrying your cousin would be a sin.
However, if you believe that marriages can be blessed by God in His church and think that cousin marriages are allowed by scripture, then no, marrying your cousin is not a sin.
The Bible does say that we should not join together with our blood relatives (including cousins) into single households, but it also says that within certain cultures and before certain institutions were established this was often not possible or not done.
For example, Jesus said: "What I tell you about living in society: neither lend money nor place your trust in men, but give up everything, hold fast to my message and pray to the Father who gives eternal life." (John 12:25-26).
So while it is not ideal, in some situations this is not possible so instead God's people marry others within the faith.
