My partner and I live together, he's in a steady job, really excelling at it - he's even been shortlisted for an award after working there less than a year. He's really getting his life together and we're moving forward in terms of getting furniture etc. for our flat, starting to build a life together. But earlier in our relationship, it wasn't like this. He would go out on a night out and come home three days later, completely drunk, tired and sometimes injured - missing days at work, needing many days to recover. This is all when he would go out with a particular group of friends - who are drug dealers, strippers, and god knows what else. He doesn't see this group of friends unless they're going out partying. After this happened so many times and got tired of being worried sick not being able to contact him at all for days - wondering if he was ok, who was he with etc. I called it quits. In response to this, he cut all ties with the friendship group and has not done anything like it since and comes home early hours of the morning like a normal person when he does go out (which is only like once every couple of months now). HOWEVER he has just contacted them all again, apologising for his need to cut people off and is basically back in touch with everyone (I found out, he didn't tell me). AIBU to say that I'm not comfortable with it, as its probably going to take us and him backwards?
