OK, my girlfriend and I have been dating for 3 years. We had great sex for the 2 years. Recently she has been getting wierd after sex. Now she gets all distant and backs away after we do it. And after she gives me a blowjob (which happens more often then actual sex now) she gets exciting during it then afterwords, she gets all distant and almost angry. What the hell is going on with her??! Can someone give me advice here? I'm think she's thinking of breaking up although she says no...
