<human>: Okay, so here's the deal. I have been with my current guy for 3 years. Things haven't always been perfect but we do have a lot of fun together. The sex is great and we have a great mental and emotional connection. He is planning on proposing and I do love him and want to be with him.

Having said all of that, his friendship with his ex-girlfriend drives me crazy. His ex gf lives abroad across the international date line and due to his weird schedule they gchat a lot late at night. I've read their gchats (the ones he hasn't deleted since he know it bothers me and doesn't want me to see it) and most are pretty innocent/tame. My guy is a bit of a lone wolf and doesn't have a lot of friends so part of me feels bad for wanting to prevent him from having a friendship with this girl since I know she's supportive to him.

However, it's not the innocent Gchats that bother me, it's the frequent Skyping and requests for money (that's a separate post, and something he had promised me would end and has ended, I think...) that really drives me insane. Idle gchat is one thing but Skyping crosses a line in my opinion. We fought about this before and he agreed that it was too intimate and that it would stop. It hasn't, I think he won't ever give up the attention he gets from her.

This has been an ongoing issue for us; the last time we talked about it he told me he was going to write her an email and tell her the deal. That she was wedging herself in between us and that it had to end. But he hasn't written her to tell her this and at this point I doubt he ever will. I feel like I'm being controlling by bringing this up again. When I saw that they had been Skyping despite my repeatedly telling him that it hurt me was a real blow. Maybe I'm making too big of a deal here and am being too controlling. I don't even know anymore.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: I hate my bf's friendship with his ex gf; what types of friendships are normal? Am I being unreasonable?
