One other thing to remember, you are *not* at fault for her A! You both had issues in your M, but she was the one that crossed that line. Never allow yourself to think, feel or believe you caused it!
One book I like to recommend to people involved in A is "Not Just Friends" by Shirley Glass. It's an excellent book that examines A's from the standpoint of all three people involved and does not demonize or put down any of them.
