A bit of background- when we first got the internet installed at home dp joined some dodgy sites and was caught out talking to girls and flirting a lot.
It was all sorted and done with.
Then he got a bloody blackberry and yesterday I got one for my birthday I was using his phone while his mum was here to add contacts to the BBM app and he seemed really eager to grab it off me then it beeped and a message popped up from a girl asking him if he was enjoying the stag night and that she missed chatting.
DP's hands were visibly shaking when I gave him the bb back and I never mentioned it.
Then today I brought it up and he stared showing me his messages with a friend from work (to prove he wasn't in the wrong 
). Anyway I scrolled up and he had been chatting about new staff hoping they got a, "Good looking one" and "Here come the girls".
I have told him to go out for a bit it all sounds so stupid wrote down but I'm hurt it wouldn't even occur to me to find ou other men and flirt with them so why does he need to?
He is busy telling me I'm stupid and he hasn't done anything but he has even if it is just flirting online it fucking hurts me and I am so pissed off that he is maiking me feel so rubbish.
