Over possessiveness

I was in a relationship with this guy who eventually became over possessive about me that he told me not to talk to certain guys bc he knows their intentions while all that he knows about them was via me. Being possessive is totally fine by me but being over possessive just bc his man instinct had to be correct led to him starting not to trust me and I couldn't take that I brokeup..Yes sometimes guys know which other guy's got what intentions but I believe I should handle it by myself I just need his support not his directions as to what I should do. We fought over it big time he made me feel trash alot of times only bc of the 'guy' friends that I had..Other than that he was a nice guy but my bf not being able to trust me is a huge no no to me..According to me I did the right thing what do you guys think? It's been 1 month now all the feelings I had for him are slightly going away except for the ones which are physical and I don't know what to do about that
