I've known this guy let's call him A since middle school, we were always together as friends but in the 7th grade I started to have feelings for him. Once we got to high school we haven't really talked. Fast forward to now my senior we started talking again. I know he is in a serious relationship, however we've been texting in a flirty way. There are times when he asked me for pics and I would send it. This one time A asked me if I could "please" him and I said no because I was texting this other guy he got mad and said "you know what don't hit me up anymore" I asked him if he was jealous that's when A blocked me on sc. Then the next day he unblocked me and added me back, I asked him again if he got jealous and he said he did. But he is in relationship like why should you be jealous if you're in a relationship I'm the one who is supposed to be jealous. Two months ago he said we should start talking as friends and nothing more and I understood his decision, but not even in two weeks he lasted. He kept asking for pics and my dumbass self keeps sending. Now this weekend we are supposed to hang out.

I know what I'm doing is wrong, I know he is in a relationship. But for some reason I can't stop it. I really like him and my friends says he should just break up with his gf already. And I feel so dirty and I'm not proud of myself. Call me whatever you want, but don't you think he should break up with his gf if he is looking pleasure from someone else.
