Hi,

Sorry to hear about this. Right now your girlfriend is probably blaming herself for what's happened, you've got to be really non judgemental with her. I know it's tough, it feels like you are being punished in one of the worst ways possible for something you didn't do. Wanting to make love to the person you love isn't wrong. It can seem that way though, but it is a very health human emotion. What's happened to you girlfriend I'm guessing is the worst thing that can ever happen to a female. I can only imagine how she feels, she isn't going to want to be intimate or affectionate. Give her a hug and tell her you really care about her. I guess in time she will open up with little things, if she does make sure you don't look at anything in a judgemental way. She doesn't want you to judge her and she probably doesn't want you to judge her dad either. Instead just listen to her and empathiSe and show support, say things like "I'm so sorry you feel like this, I would be hurt if it happened to me. I've always got an ear to listen, a shoulder to cry on and plenty of hugs just for you."
Remember to find a healthy way to let out your frustration. Go the gym, watch your favourite movie. It will be really though on you too and it can affect your confidence and self esteem if you let it, instead look at productive ways to deal with frustration.

I hope this helps.
