chero.....can you make your own plans for the weekend that does not include being around someone who is drunk?
he is going to do whatever he wants to do about drinking....you can not change that. but you can change how you react to it. you can involve yourself in focusing on things you like to do....
what is miserable is spending the entire weekend trying to make him stop. or outwit him. or trying to change his mind, or make him see the light, amen.
i've done it all, sweety.....and it just don't work. turn all that focus on yourself and have a good weekend.
