Girl that I'm seeing suddenly doesn't want to be intimate
For the past six months, I've been seeing a girl. We went dancing, visited places, went to the movies, and so on, but we are not officially in a relationship. We do a lot of foreplay, but no sex, because she feels that you shouldn't have sex until after marriage (she is Catholic). I can deal with this, but recently she suddenly told me that she doesn't want to do any of the more sexual stuff. She still wants to see me, talk to me, maybe even kiss me, but not do anything more than a simple kiss now and then. She says that she feels bad that she was ever doing stuff like this in the first place, and that she's trying to "behave".
I like her, and I want to do stuff with her, but this sudden change of pace would be difficult for me. I told I wanted to do something separately tomorrow (we were originally planning on seeing eachother), and she wasn't too happy about that. She eventually guilted me into going with her anyway, most because I want to talk about this more in depth. I don't know if I can see her so much without having the more sexual stuff. Is that selfish? What should I do to make her understand how this is important for me (she thinks that wanting intimacy like this is a 'guy thing')?
