An alcoholic can push the person that loves them away. They only need the alcohol and not you. They can become distant and cold. If you love this person, it can be hard to live with or accept. You have to watch the person move farther away from you while you sit and watch. Soon, you are so far back in line that you feel as if you are all alone with no one in your life. This can happen to even the most loving couples. Alcohol does something to the brain and the body that changes a person. They withdrawal from reality and live in their own little world without you.
Never force yourself on the alcoholic if they do not want to be close to you. If the person you love does not want you, there is nothing you can do to change it. The person is not going to change their mind just because you are trying to make things work. You should never try to be with an alcoholic that does not want anything to do with you. This can anger them and makes things unpleasant for both of you. You have to keep your distance and if they want you near, they will tell you. The hardest part is waiting.
