Current relationship

I just feel hurt now.

Hi guys, I usually don’t talk about my personal relationships and stuff on here but I need y’all help. I need to know when enough is enough when I.T comes to a relationship. It’s my first boyfriend and he has bad trust issues. We’ve been dating for about 4-5 months and it’s still constant. Yeah we love each other but seems soo I know. I’m kinda fed up with I.T from him always assuming stuff about me. I’ve never cheated on him, I treat him so well that I will never do anything to hurt him period. Constantly he thinks I cheat on him when I’m home and not with him. I cry to much to the point where I know my tears are not worth I.T. I’m hurt and idk if he knows I.T. I just don’t know what to do anymore. I need help. I need good advice. I know that he’s been fucked in the past but that was 4 yrs ago from a girl that was his freshman year. He’s 19 now and graduated. Help me please.
