In a nutshell, you must quit enabling him. As previously said, you cannot control him, but you can control yourself. This indicates you should not purchase him alcoholic beverages. Make it difficult for him to obtain it. Don't lend him the car keys or pay any of his home expenses. Don't call in ill to work for him or make any excuses for him. Remove himself from social events where he may need to drink alcohol to fit in.
The more you restrict his access to alcohol, the faster he will quit drinking it. Remember, you are helping him by not giving him an excuse to drink.
As for his drinking before you cut him off, this is something that takes time to change. You cannot suddenly stop your boyfriend all together without causing serious problems between you. If he has been drinking regularly for several months then you should try and wean him off gradually. For example, if he usually has one beer after work then try and get him to give up one episode of television after work instead. This will help take the pressure off going to sleep with an empty stomach every night.
Finally, remember that you are only human and it's easy to make mistakes when you're angry. Avoid saying things you will regret later. Take time out to cool down before talking again.
These are just some of the suggestions that come to mind. The point is to help your boyfriend stop drinking alcohol so don't be afraid to ask for advice.
According to what you describe, your partner is an alcoholic (for additional information, see the alcoholism symptoms section), which is now universally recognized as an illness, and it is not something you are responsible for or have any control over. Alcoholism is a chronic condition that can be treated but not cured. It involves both physical and psychological aspects of a person's life.
When someone is addicted to alcohol or other drugs, their addiction controls their lives. They may go through withdrawal if they stop drinking or taking drugs abruptly. In addition to the problems caused by withdrawal, there are also programs available at rehabilitation facilities that can help an addict overcome their issues with alcohol or other drugs.
An alcoholic or drug addict cannot stop themselves from using alcohol or drugs. Instead of being able to choose whether or not to drink or use drugs, they are forced to rely on external forces such as social pressure or anxiety levels to determine how much they will consume. This makes them feel powerful when they drink or use drugs even though it is having the opposite effect. Over time, an alcoholic or drug addict builds up a dependence on alcohol or drugs. Without drinking or taking drugs, they experience severe headaches, nausea, irritability, and other symptoms that indicate an addiction is happening.
People who abuse alcohol or drugs often suffer from depression and other mental health issues.
How to Encourage a Boyfriend to Quit Drinking
Things that can be useful
The writers of the Alcoholics Anonymous book encourage women not to tell their boyfriends or spouses to stop drinking in the "For Wives" chapter. The irony of living with an alcoholic lover is that you have no control over his drinking. If he regards you as a nuisance or a jerk, your prospects of assisting him are little to none.
Women have no legal right to prevent their husbands or partners from drinking alcohol. If she tries to do so by calling him names or leaving him, this only makes matters worse for her. Women can try and help an alcoholic by getting him/her into treatment or by staying away from him/her when he is drinking.
In conclusion, women cannot stop men from drinking alcohol. They can only hope that their partners will learn to control themselves and that they won't hurt themselves or others because of it.
