Help

My partner and I have been in a long distance relationship and we are about to move in together, we have spent months at each others places during the relationship so that isn't a problem, but he left his facebook logged into my laptop and i have returned home and seen that he has tried to contact his ex girlfriend whom he recently referred to as a 'stuck up middle class bitch' you can feel the hate right? or at least i thought so. He contacted her in May when we had already decided to move in together and he tried to speak to her whilst i was in hospital having major surgery, picking on me at my weakest point here. should i confront him about this, could he of been asking for his stuff back or something because i know she still has his nintendo wii, but it was a simple 'hey' not a 'hey can i have my blah blah.. back' which to me sounded like he was trying to contact her to speak to her. we have been together for a year and i dont want that to go to waste so what do i do? am i not good enough for him, this has totally stumped me.
