Just went and saw The Wildhearts for the umpteenth time. I love that band.
Saw them with my housemate, my ex and his fiancee.
Me and my ex went into the crowd and were dancing away and I felt so bad about having fun with him. My housemate's been friends with him since forever and noone ever says anything to her about having a laugh with him.
It just pises me of that we're ex's for a reason but everyone assumes that we want something to happen again.
I'm mates with his fiancee. I think he's much better off with her than he ever was with me. But noone seems to get the fact that we're over, we are literally just friends, the thought of something happening between us makes me laugh. But there's so many memories (like wildhearts gigs) that we share.
Am I suposed to ignore the person sat next to me because we had sex once? We've got 5 years of history, I cant ignore that, I still love him to bits, tha same as I do all my other mates, but I think of him the same as I d my other mates. When we were together I regarded him as my best mate. Ijust feel so crap that I have to give up one of my best friends for the sake of everyone else.
I can't have fun with him now without feeling bad.
It's a bag of shite.
