Man that's a rough spot to be in....
I think you should check your email for starters. Don't worry about things you don't know, ya know?
Accept what happened. There isn't an undo button on life. Read this email she sent back if there is one. And go from there.
I understand where you are coming from, and I can't say that I did much better in my situation, when something like this happened to me. I never talked to Jessaca again after that. Mostly on her accord. I felt at the time being blunt was the best thing. While it might have been it still didn't set right with me that I had done this. Not really my style.
You can see how things play out.
OR
Send an email and say, 'did you get my email? or 'want to talk about it?' To atleast let her have some closure about what you said, and leaving you feeling like you followed up responsibly and didn't send a hate email, blankly.
OR
Live with it.
Judging by my sentence legnth I'm think #2 might be fitting, cause we know your a nice guy

And its obvious you don't want someone walking around who hates you.
I think explaining yourself atleast on the phone would be the middle way between face to face and never again.
Sorry things went bad for you. You'll be okay and will do the right thing for you.
Good luck man
