First of all I wanted to say thank you all for taking the time to answer my problem, I really appreciate all your help and advice.
I know its wrong but it feels like "he has won" even though its not a game, he probably thinks it is knowing him. Im 5 foot 10 and weigh 8 stone at the mo, I'm not eating or sleeping while this guy puts it about with this woman. I try hard not to think of them on there little "trip" without wanting to rip his head off if I'm honest. I feel so used and hurt, like they are both laughing at my behind my back, I just want to die so the pain is over for good
