If you are thinking about leaving and I know this seems really harsh but you have to cover your **s. If you don't have proof of his drinking it's your word against his and you are going to look like the vindictive ex-wife who doesn't want her ex-husband to see his son. (I know this because my Mom went through this with my Dad, and my husband went through this with his ex-wife (she was the drinker)). Guess what if you don't have proof of his problem, then he's going to have regular visitation and you won't be able to protect your son if your husband is drinking around him. I left an abusive relationship only to have no control of the environment my son (my oldest son) was in and sometimes I wish I would have stayed to be able to protect my sons’ best interests. I felt like I saved my self at my sons' expense. (Now he's a great Dad, he got couneling for his anger problem and we get along great). Divorce can be very ugly, I would suggest...

1. explore ALL other options first, counseling, alanon ect.
2. If you’re going to leave, get lots of proof first, police reports, video taps ect. (expecially proof of him driving drunk (how does he get home when he's drunk)) If you don't the courts will NOT believe you. If you do get proof, they'll make him get help, he will still be able to see his son it will just be supervised until he has proven himself clean to the courts.

Again I hate to sound so negative, but speaking from experience, you’ve got to CYA (cover you’re *****). And I am not the vindictive ex-wife, my children's safety comes before anything. My ex-husband is now one of my best friends (we settle everything ourselves, outside of the courts, even child support) I'm only telling you this so you don't think I'm a vindictive person and trying to give you advice to be mean, I believe you've got to protect your children at all costs.

Good luck
