Dear diamonddog:

A possibility is that you send her a very short message, an email, saying you very much regret having mistreated her, that you experience lots of regret and are sincerely apologizing for having mistreated her. If you make it a short message, she can, if she chooses, ignore it. No harm done to her.

If you send her such a short message (no details in there about how you mistreated her and how you feel beyond mentioning regret) and IF she responds to you, somehow asking for more details, more information, THEN you can send her a more detailed email.

What do you think?
