You're welcome. I'm hoping what I've written is of some use to you.

I can't give you a definite reason for your exes behavior. Only she could do that, but you may never know why she's chosen the course she has. Like I said, that's a good thing because her life isn't for you to become tangled up in anymore. You're free to do as you please with who you please who wants to spend their time with you.

Don't waste your time casting value judgments about your ex, or anyone else for that matter. It's a waste of time and will only serve to make you embittered by your experience.

You're right. You do have to focus on yourself. What do you think would help you move forward?
