My boyfriend and I met because he was a friend-of-a-friend, and later i found out he had a crush on her. He liked her basically all of last school year and even went to prom with her. They've stayed friends and sometimes she send him snaps. Sometimes he'll bring her up in conversation.

I can't help but feel insecure and wonder if he still likes her. I used to be friends with her until we had a falling out and became more acquaintances. He told me that after he and I started dating that she started texting him and showing interest in him.

I don't like feeling his way and it's making me distance myself from him, but I don't want to bring it up and make him think I'm just being petty.

Any advice on what to do?
