Graduation Showdown

My graduation is July 15. So for my graduation I’m worried that my ex lover is going to cause a huge scene with my current bf.

Let me explain why...

So when I was with the other guy he was super nice and always wanted to talk to me but then he started getting distant and didn’t txt me or talk to me like he normally does but I brushed it off. After that he would flare up and get mad at me and telling me that I’m his and no one else’s. That was fine with me. Then it got worse. Anytime that I would bring up a friend’s name he would flip out and asked me, “ who’s more important, your boyfriend or that other person?” And it pissed me off.

Recently I was able to get back in touch with one of my old friends I used to go to school with and of course, it was a guy. He lost it and told me to stop talking to them and to tell them that I had a boyfriend. I said that he needs to stop being so possessive over me. He said no and to stop txting them now. I didn’t want any more fighting so I told my friend that I’d txt him later.

The next day when I was in the middle of txting my friend, he called and he yelled at me and told me to tell him why my friend was so important and then I did. He called me a slut then hung up. After that I told my friend what happened and he called to calm me down.

Then after that day I called him and told him how what he did was completely unnecessary and immature. He told me that I was a self-centered selfish bitch and told me that he can’t believe that he ever told me that he loved me. Then he blocked me.

I was crying for awhile after that and called my friend so he could help me calm down. We talked for awhile as I called down. He asked me what happened and I told him everything. He got beyond pissed that someone would ever do this to me and asked me if I wanted him to do something about it and I said no.

Now me and my friend have been dating since May 6 and he wants to come to my graduation and I obviously told him yes. But now I’m worried that when they see each other, that one of them is going to cause a fight.

WHAT DO YOU SUGGEST I DO????
