Just chill out. I'm been with my girl going on a year now and we're great. I get jealous easily but I never get jealous around her. I used to, but I know she isn't going to leave me. If you're really uncomfortable with what she does to make you jealous, just talk to her. Let her know just how you feel, and if she understands, she'll change. If she doesn't, it shows she doesn't care about you, and you're probably better off without her.
