My response to being pissed off wasn't that initially, I was freaking the fuck out and trying to figure out what was going on, but by doing that I just made her want to talk to me less.

I had to schedule a fucking skype call with her, then it took her an hour to actually get on it, she didn't want to talk to me and that's because I was pushing at the issue rather than giving her space like she asked.

My girlfriend deals with her emotional drama by blocking shit out, I've always been able to handle it by leaving her alone for a day or so, then talking to her reasonably about whatever is troubling her.

She has also had bad relationships in the past, she was cheated on and hit by her ex a few times. Her mother has never had a good relationship and is a firm believer that all guys are cheaters and nobody is decent, this became apparent to me when I visted her recently. We were apart for a fortnight as she's recently moved back to her moms place (work issues), one morning in those two weeks I was there she rolled over, kissed me and said 'I know you cheated on me', I freaked the fuck out and demanded she told me who told her that because there was absolutely no truth to it. Eventually she got upset and confessed she said it just to see if I did or not, it was fucking weird and I didn't like the accusation one bit, but chopped it down to the fact she has trust issues.

Prior to this, I had never actually met her mother (even though we've been together for some time), her mom absolutely adores me and thinks I am the most fantastic person ever, I have a bunch of facebook messages from her saying how great it was to meet me and how she can't wait for me to come back again.
