I'm 18. I met my current girlfriend almost two years ago, and we're in a pretty serious relationship I guess. I love her, this I know for sure, but am not entirely sure I love her in the way I should. When I think of her I don't feel the 'butterflies' or whatever that I get when I think of certain guys. I've only ever dated girls, and never entertained the thought of dating a guy. Basically my two main issues right now is that I'm questioning (these thoughts are intrusive man. I cant stop), and I think I have to break up with a girl I love and really don't want to hurt.
