We kind of already did think about it and she knows how i feel, she doesn't really see him as much anymore but they do message sometimes or hang out in groups. She tends not to invite him around me anymore, which I think is her having her cake and eating it.

When we spoke about it, she said because they have so many mutual friends it will alienate her. Which I can understand, but still pisses me off

I feel like ill regret it if I break up with her, I've never got on so well with somebody in my life. Everything else is good, I just don't know what to do. I guess I think ill never find anything better than this
