I'm a bisexual girl and there is this girl I really like, stuff's been happening for the past two months but we're not together or anything yet and we haven't had a chance to see each other in person for a bit because of the holidays and that. Anyway one of my guy friends used to like me a lot and we had a bit of a thing before I met this girl but it never really turned into anything and I'm glad to be honest. Last night he randomly added her on facebook from my profile and I know he's only done it to try and score (doesn't it just annoy you when people do random adds to try and get a shag?) with her. And she accepted for some reason, despite the fact she keeps her profile really really private. She's pretty much gay and she has done stuff with guys years ago but I don't think she would anymore. Yet I still feel really jealous! I was talking to her on her facebook page and I could see that they'd been chatting quite a lot too. I know I shouldn't feel jealous because she doesn't really like guys anymore but I still feel like that. It's also pretty annoying that I KNOW that he's just trying to score and use her, he does that with a lot of girls and I don't think she realises but it's not like I can just tell her because she'll think I'm jealous (and let's be honest, I am). She doesn't always realise when's she's being taken advantage and she's a bit vulnerable because she's been through some stuff in the past year. How do I stop feeling so jealous of this guy?
