Relationship Issues

I’m not the type to tell anyone my problems, but, I’m a teenager who’s having problems with a boyfriend,

A few weeks ago me and my boyfriend abruptly stoped talking.. I don’t know why and still don’t know why but, to make a long story short, I got lonely and I didn’t have any one to talk to or friends.

I don’t go out much because I’m hom schooled and I just prefer the house anyways, but I went out to the library since that’s the only place I really feel comfortable going and the only place I feel myself at. But when I went I met a guy and we started talking, we instantly became FRIENDS. But my boyfriend called me one night at like 2:30 in the morning and told me the reason why he wasn’t texting me and things like that or whatever. I felt like he should know that I was talking to another guy while he was gone.

He got mad, but then I reassured him he was just my friend or whatever, but he still got mad. I sent him texts of our conversations with each other and everything.. but.. he’s still mad.

I’m thinking should I let his ass be mad or should I apologize for what I did.😩
