Well imagine this, you smoke cigarettes all the time, you're addicted, you get a boyfriend who tells you he doesn't want you smoking. Are you supposed to just quit cold turkey right then and there? No it's impossible. Or you have an apartment, live by yourself, then your SO moves in with you, now you have to get used to there being someone else in the house. I understand where you're coming from, I really do, I was in the same situation, but it's not like he doesn't care, it's just hard for someone to completely stop a habit they're so used to doing just like that Just talk to him again, if he doesn't seem to care or blows you off then maybe really reconsider being with him Or reach a compromise

You've already set your boundaries, he continues to disrespect them and doesn't seem to be slowing down, so you'll need to stick to your word and leave. Why care about his feelings if clearly he's not considering yours? When my husband and I were dating, he'd had a couple nights where he blacked out. Those following mornings I was nowhere to be found. He quickly got the hint and changed his ways. You gotta communicate and stay consistent. 👌🏼 

Just a question what makes you uncomfortable you think he might cheat or he gets mean and abusive when he comes home drunk? ... but you can't force him not to go out if he loves you and respects you he should either stop all together or if you guys come up with an agreement that it just can't be every weekend or even bring you with him if you want to go out ..And just a tip that I did so he wanted to stay home was to do things with him maybe get dinner and drinks stay home get drinks or just dress up in something sexy and have a good night with him!
