I need your help to figure out what’s going on with my relationship, Lovelies! Here’s the scenario:

My boyfriend once hooked up with a girl that he was interested in, before I even knew him. The only reason they didn’t date was because said girl rejected him, not because he stopped crushing on her or anything. Regardless they became friends again, and also became very touchy.

A year later I started dating him, and we were clearly exclusive. But this girl was still there, and she occasionally kissed him on the cheek! At first, it only happened at parties when she was tipsy. Then she started doing it while sober too. And sometimes my boyfriend kissed her back, or blew kisses to her.

So, trying to be mature about it, I told him this wasn’t okay with me. After that he promised at the next available opportunity he would tell her to stop. But, it actually took him 3 months to tell her this wasn’t not okay.

Side note: This boy and I have been broken up for almost two months, but I can’t get over this. He has done things to show me he won’t let it happen again, but it hurt me so much when it did happen. 

What do you think, Lovelies? Am I allowed to be upset? How would you react?
