Recently got dumped because she really liked me but wasn't romantically attracted to me. It could of just been not a good fit (conversation didn't flow easily, something that is normally not so much of an issue for me, and she mentioned that I make her nervous occasionally which can't be good). What made it worse, she said that I'm the perfect guy for her (attractive, good job etc.) which really hurt. How can I build a romantic relationships with new girls going forward?
