So I dated this girl for a few months, we split, but started hooking up again. Anyways, one of my friends have started orbiting around her pretty hard, and while I'm obviously ok of her having many male friends (as I have many female) she seems more excited to hang out with him, they talk a lot, and he's willing to drop everything to hang out with her.

He's admitted he crushes on her a little bit (along with her friend, he doesn't get a lot of female attention) and maybe it's because things have been a bit rocky with us, but I'm having a hard time trying to not be jealous.

I realize a lot of my own insecurities are shining through, but how do I keep my cool? She says they're best friends now, and I worry she might be crushing on her new orbiter (which may or may not be the case) How do you handle this?
