I have to rant a little... Are any of you ladies territorial over your man? Like, what's mine is mine and he is my man so stay away? haha, my boyfriend has this friend and even though I know for a fact there's nothing going on between them, when the girl is around I get very clingy and wanna fight her because I know she wants him (she said it herself) but she can't have him...I don't know...I'm ranting sorry haha
