I can’t really offer good advice without knowing more, but I will do the best I can.
I’d like to know how long you’ve know your SO? How old are you two? How long has he known his friends? How did he meet his friends?
It is not cool that they pressure you to drink. Does your SO drink with them? How much do they drink? Do they drink to the point of passing out? How often do they drink and how often does your SO drink with them?
Your SO should be able to support you when you tell them their behavior is not cool and you want them to stop. He should say the same thing. They may be afraid of losing another one of their group. Do they have jobs? What do they do?
I would worry if your husband drinks a lot. If he hangs out a lot with them. Like three or more times a week. I think that’s a sign of an alcohol problem.What’s he like when he comes home from a night out? How different is he?
Have you told your SO how this makes you feel? How you feel angry and jealous? At the heart of this it is an issue between you and you SO, and the only way you can work on it is to talk honestly to your SO about the situation. You don’t accuse him of anything or use the word “you” at all. It is about what you feel. And what he feels. And negotiating a solution.
What do you want? Do you want them to stop talking to your SO about dumping you? Do you want him to stop going out with them so often? Or go out on different nights? Do you want your SO to stop drinking? Whatever it is, let him know, but be prepared to bargain. You won’t get everything you want. Don’t threaten him with any ultimatums and let him know you really love him, but this hurts you and what can we do to make this situation better and heres what you would propose.
If you can’t talk to your SO about this, that’s a real problem. If you can, you should be able to work it out. All you have to do is figure out what you want, and then talk to him, and be willing to compromise.
