Relationship

Honestly need some help..... I’ve been with my current boyfriend for 15 months we generally have a great relationship until he wants to go hang out with his friends( every Thursday) well I freak out and start getting in my feels. And we always end up fighting, I’m terrified of him cheating on me and lying to me ( he lied to me twice when he was with his friends before we started dating, it was something g stupid) however, every time he says he’s leaving to go hang with his friends I panic and automatically think he’s going to leave me for good. I do this because that’s what my abusive ex boyfriend would do to me. Lie, go out to bars, and cheat on and then come home and yell at me non stop. Therefore I built a wall and now I need help dystroing it. I dont see my current boyfriend ever cheating on me he just cares to much he seriously hangs out with just guys but I can’t seem to get that out of my head when he says he’s going to hang with his friends. I always jump to the thought he’s going to lie and cheat on me. I hate it.
