The phrase "partner" has a nice ring to it. It means you're with someone who wants to spend their lives with you. A "boyfriend" or "girlfriend," on the other hand, is someone you fondled in high school at a house party—and it was serious since it occurred more than once. Now that you're adults, you've both moved on. Yet your partners still think of themselves as your friends and only want to be with you.
The implication here is that there's something wrong with wanting to be with your partner forever. It's normal to want to share your life with someone, but only a fool would think it was okay to stop looking beyond them. Relationships are hard work and require patience and trust. Only someone who is willing to put in the effort needed can hope to find true love.
In conclusion, a partner is someone you want to grow old with, while a boyfriend is someone you fondled in high school at a house party—and it was serious since it occurred more than once.
"Partner" implies something more serious—someone with whom you are not married (or even want to marry), but who is a step up from a boyfriend or girlfriend, which might seem a little more casual. To describe a woman as your "girlfriend" doesn't necessarily mean that you plan to get married to each other; it just means that you're good friends and have a mutual attraction.
In other words, a girlfriend is someone you've got a relationship with, but isn't your wife or husband. So yes, a girlfriend is a partner.
Your boyfriend is the guy you're dating (in a committed romantic relationship with). He may be your husband if you both decide to get married.
The word "boyfriend" comes from the Latin word puellus, which means "young woman." In English, this term has become more specific over time. Today, it is used to describe a young man who is a friend or crush.
In old English, there was no difference between the words "husband" and "wife"; they were both called "mate." But by the 13th century, these terms had come to mean a man who married another man's daughter or sister, thereby inheriting their family name and property. Such marriages were often not accepted by society, so these men usually did not have many friends. They tended to live alone in grudging respectability until they died.
Today, people use the word "husband" to describe the male partner in a marriage. The word "wife" is reserved for female partners in marriages. A husband and wife are two people who marry each other. If someone says they are your husband or wife, then they are telling you that they are married to you.
Beyond the words employed, there is no distinction between strictly dating and being a 'boyfriend and girlfriend.' Being a 'bf and gf' is a title, a description used to denote ownership. Because there is just one of each in the sentence, the phrase "boyfriend and girlfriend" indicates exclusivity. However, this isn't always the case; sometimes two people may have a close relationship but not be boyfriend and girlfriend.
The term "boyfriend" comes from the Latin word puellus, meaning "young man." The term "girlfriend" comes from the French word garce, which means "girl" or "lass." So, technically speaking, a boy friend is a young man and a girl friend is a little lady. But since they are usually only referred to by their first names, they are often called a "buddy" or an "chick friend."
In modern usage, the terms "boyfriend" and "girlfriend" are used to indicate a person with whom someone is in a romantic relationship. Even though people may call other people their "boyfriends" or "girlfriends," only those people who are involved in a romantic relationship should be considered for that title. If you're just friends or nothing more than friends, then you shouldn't use the term "boyfriend" or "girlfriend" to describe your relationship.
People sometimes get confused about what it means to be an "exclusive" boyfriend or girlfriend.
