My husband of 7 years and father of our 17 month old son has recently (in the last few months) started to go out to the clubs with his single friends and get really drunk and stay out all night. This morning he didn't get in until 6:30 am and didn't so much as call or text me. I was really starting to worry he got in an accident or something.

I don't mind him going out with the guys and having fun but getting too drunk to drive and staying out so late is really not the kind of behavior I approve of.

How can I help him see my point of view? I don't mind him going out sometime and having fun without me but I don't like that he's going to bars and clubs all night getting drunk.

(side note~ I really don't think he's cheating but in the past we have had a few problems with him trying to meet other women, online mostly) So his helps fuel my dislike for him going out and dancing with other women while he's drunk etc.

What should I do, how can I deal with this?

Tell him not to bother coming home next time, Make him sleep on the couch, leave him if he does it again.

You let him know this is unacceptable to you. He needs to decide if he wants to be single or married. You will not put up with him coming home in the morning after a night of drinking.
And mean it. Otherwise he establishes a pattern and you allow it.
