agree with Amg, it’s not a realistic request and he should be allowed to get drunk/wasted and have a good time with his work buddies. what’s the reasoning for you not wanting him to get drunk?
My husband occasionally goes to training 3 hours away. Sometimes he's gone for a night, others a week. Just depends on the class. I book him hotels that have a bar, he never goes. He wouldn't get wasted, but I wouldn't be mad if he had a beer after class. he's a grown ass man, he's capable of making his own decisions. Just like if he told me the work crew wanted to get together and grab a few drinks, he could go(I'm friends with his coworkers so I usually go too but if I didn't want to I wouldn't care if he did).
Firstly, if he agrees to not get drunk, then he shouldn't do it because that's how you lose trust in him. Secondly, I'm guessing it's either that you have fear of missing out and want to be doing it with him or it's a safety thing and you worry about him doing it with people that won't have his back if something goes wrong. I think you need to ask yourself some hard questions and figure out why, then go from there.. I suggest seeing an educated therapist and seeing what they think and how yo move forward. Maybe also couples therapy because your husband shouldn't be agreeing to something and not following through and worrying you.
Just my opinion … you fear what will happen when he gets drunk. You have to sit with the why because the request seems unreasonable. While respect is a must in marriage so is trust. Don’t make the your marriage a prison.
why can’t he enjoy himself if you are not there? I am not sure of what’s the reasoning but does not sound like a realistic request. i think probably you need to have a day were you have fun without the family around ❤️
