I am 28 My Bf was 35. We had what i thought was a great relationship we were together for about a year and a half and prior to that we were good freinds for about 2 years. At the begining of our relationship i caught him going into the bathroom with about four other guys, i know a few of this guys did cocaine. I asked him what he was doing and he insisted he didnt do any drugs and that they just somtimes all took a piss together. I never belived that and after that i was always suspicious of these particular freinds. I always got along great with his other freinds, his work friends his family but i didnt not like it when he would hang out with these particular guys. For the first year or so they hardley came around. and when they did They used to come to his house and do drugs in the bathroom and i would make sure my bf wasnt doing anything, He would never tell those guys to go home or not to do that stuff. Most of our fights were caused because of these particular freinds that did drugs. about 2 months ago we finally had a big blow out over these drug freinds and he said i was trying to tell him who he could and couldnt see and that i shouldnt make him choose, wich i didnt i just asked that he tell them not to bring cocaine around. he said thats not fair to him. He said that i degraded him by accusing him of doing drugs and that his freinds know he didnt do that stuff. But one freind said to him before since when dont u do it.
So I broke up with him about 2 months ago then decided i would forgive him but he said he didnt want to get back with me because we would never be able to get over this issue and i would never trust him over drugs, he also said that i become to explosive and seems like he is finding minor issues wrong with me, we hardly had fights except over drugs and these particular freinds. I know latley he has been going out with this group of guys. He has lost alot of weight latley and said its because he cant work out and he is running more. He wanted to stay being freinds and would text me often. i found i was doing most of the work though in being freinds and he never invited me out. He said he loved me and his family thinks he should work it out with me but he said he doesnt want to and they dont know cause they werent in the relationship with me and dont know how i am lol because i get angery over drugs. When people ask him what happened with us he doesnt explaing and only says "its Too Complicated" About 2 weeks ago i started no contact. he text me a few times saying hi and hello but i didnt answer. What is everyones advice and what do people think of this siutation?
