Too Jealous...

I trust my boyfriend. But there's this girl that's all fucking over him. ALL THE TIME. He didn't even know her until I introduced them a week or two ago and she goes up to him all the time and pulls up her sleeve and says "I'm sorry, I cut.. I'm so depressed" and it pisses me off. She's told me before how bad she wants a boyfriend and to have sex and how jealous she is of me. I don't know. I've always had very bad jealousy problems with EVERYone. But today they're hanging out at the park together, because she was there and he was walking around and saw her. I'm so sad. I dunno. Guess I just needed to vent.
