Are you sure it is her and not your h? I have this odd feeling that it is your h wanting to see what you've been posting and receiving. The reason I think that is that my xh, during one of the few times he was in my house before really going of the deep end, had some type of command string put in so that he could view emails from his office. Once his mother told me what he had done, I found the string and deleted it.
They may say that they don't want anything to do with us, but they can't let us go. It's very sad to think that they are like this, but it's so true.
Glad you had a nice Easter and I am very sorry about the email nonsense.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
