I still don't trust my partner. We've been together about a year now. Every day that goes by, I think 'what's he doing?' or 'who's he with?'> He chats up women on the internet. I know about this and kinda make jokes about it, but it kills me. I can't help thinking he's trawling for someone to f*ck whilst I am not there. We live in different cities. Why can't I grow up and just chuck him?
