I have an issue with a friend. Is this right or wrong?

So one of my best friends has always had this issue...she didn't like any of her close best female friends talking to any of her close guy friends. Or any guy she liked for that matter. For example, once she had a crush on this guy and I added him on myspace just to see if he was a douche or not. Which he was btw. I didn't add him cuz I liked him or for any reason like that, I told her that but she flipped out anyway and told me to delete him right away. Now after three years of knowin her she has finally "allowed me" to know one her guy friends. He's really cool and we talk, but we are just friends. Then we all went to hang out and later she told me she thought he talked to me too much and she felt like she was uncessary to our company. I think she's being ridicoulous and idk what to do. She's been dating her boyfriend for more than a year and it doesn't make any sense as to how she doesn't like any of her female friends talkin to her guy friends. Weird huh? I need some advice.
