I'm glad to hear you made it that far with this particular girl, but if I were you I would back off. The last thing you want to do is give her a reason to file an assault allegation against you. Sometimes women say things and regret things later. Instead of giving an emotional and needy response, give her a "I understand." response. I know hindsight is 20/20, but hear me out. The last thing you want to do is make a girl feel uncomfortable. What you have said is, "Oh I didn't know, but its cool. I'll get out of your hair."
Hope that makes sense,
