I'm a little offended.

This is not a big issue, at all. I'm just a but put out. So, my boyfriend and his friend and I study together. Every few hours, we take a break and play various video games. I play one and the friend plays another (just personal preference). My boyfriend always plays with his friend, which is fine. But I was originally invited to these study sessions to play my game with my boyfriend during the break. I politely asked my boyfriend today if he'd ever play with me. He said no, because he doesn't want his friend to feel left out. But what about me feeling left out? Am I being stupid about this? I'm not mad or anything about it, just wondering what you guys think.
