10 pts Is there any chance that I can win her back?

Ppl make mistakes! But the important thing is too learn from them, if this guy is really as bad as u say he is, she will eventually see that... And yes first impressions do have an impact on future dates! It's really up to her. I say kinda like back off alittle bit, give her time but still be there for her! That's a biggy. Maybe she might change her mind about you later on once she sees who you really are as a person! Just gotta keep the faith!
