Is My Man Cheating? - He Uses My Insecurities Against Me

I dont know why but so many things confuse me. I have slight insecurities but for some reason I feel my gut says yes . My boyfried , I feel he uses my insecurities as a way to gaslight my questions. He won't put our picture on his profile and has blocked me because I freak out when I see woman friends. He lied about washing his sheets and often violent when questioned. He recently bought new tee shirts. I have been with him over a year and never did he buy himself clothing and now our relationship is on hold

Please help!
