Wow, she sounds like a bitch. If I was at work with her, DON'T talk to her, ignore her completely and after a while she might be like :wtf: . Most probably she will want to talk to you after a while. You can do better, she sounds like a loser who can't get a guy her own age.
Oh, btw, you might just email a copy of the first letter she sent you from a different email address, so she reads it, but she's probably :bs: about not reading another letter of yours. In the first letter it says that if I ignore you, i don't mean it, blah blah
