I 22f and my bf 27m have been together for a little over four months now. We talk every day and are very... compatible. I am completely in love with him but we have always had issues with arguing and it's only getting worse. Most of the time it has somethign to do with boundaries and trust issues. Tbf abt the time we made thigns official I met this guy who played video games and i plaeyd a few games with him. we never met 1 on 1, and when he expressed interest in more I told my bf. I'm prtty bad with boundaries so I didn't cut hiim off as quickly as I shoudl have. I also called him a final time even tho my bf said not to talk to him. That said, ever sine then my bf constantly brings it up and says hes worried that if hes not talkign to me ill go find someone else behind his back. I feel like we are arguing every other day and I don't like how he name calls (ugly lil girl, etc) or says he hates me when hes mad and answrs all my questions wth questions or just idc, its fine, cool, until the name calling starts. He asked me to trust him bc he will change, but he said he thinks I chose someone else over him. What a I supposed to do now? How does the future of the realtionship look?
TLDR: I didn't reject a guy who I thought was a gmaing friend fast enough and now my bf doesn't trust me. We were already having issues with what he says when angry but now we argue more and it's affecting my self esteem
