Are feelings the same.

I will start off by saying that I am a female and I am with a female. We have been together since June 13, 2008. Before we hooked up like that we messed around and did things, broke it off because we thought it would be best, then to come to find out I think I was in love with her then she decided to get back with me. When this happened I said yes and we became girlfriend’s at that time. During are break off she hooked up with this other chick a few times, who she met in that march? But since we are back together should there be a reason that they still talk even as friends? To me that is crazy what could the possibly talk about? It worries me sometimes and I get extremely jealous. every time we talk about it we argue, because I don’t want to hear anything about her and I don’t really care too, but she still will call her and what not. If I say that I do not want her to talk to her, then she will say that she don’t want me talk to this guy. What happen between me and this guy, I find different. That is because I have known him since we were both kids, and yes we did eventually hook up a couple times, and that was a friend on friend basis and has never went further. I find that it makes a difference since I have known him for years, and she has only knew her for about well 1 month before they hooked up? Is it right for me to say that it is wrong for them to be friends, but okay for me and my guy friend to be friends?
