WH,
Thanks for your updates - good to hear about your new relationship.
Sad to hear that X is still trying to re-insert himself in your life.

I like the idea of 'distraction' to describe what he's doing.
It fits my current bout of XH re-appearance in my life (trying to drag me back into a court dispute about unpaid child support - after 5 years!).

How awful to be the mlc-er, living your life in this 'stuck' position.

Sending positive thoughts to you and your kids!
