Most Helpful Girl
If u felt u treated her badly, only then u need to talk to her and sort it out. Otherwise, I don't think a girl who doesn't respect ur views will be a good partner to u. So, I think its good that she broke up with u at an early stage. If she is totally against the concept of taking it slow, it won't work out for u. U won't be happy anyway. She will keep pushing u throughout ur life.
I can tell this from experience coz my BF has similar views, and I'm totally okay with it. His style of thinking suits me very well.
