nice of you to drop by my thread over in Surviving..
you asked if the XW finds reasons to contact me if I don't her (or something like that - kids make it hard to focus today)...
yes and no...when om wasn't around our situation was much like yours..divorced and hanging out and doing things (dinner, groceries, etc..). When om came into the picture, XW became distant and totally involved in her new relationship. I didn't exist at that point and couldn't do anything right. So I didn't - I've layed low as i can and removed myself from her drama. Especially lately since the om was without a job and always around. Now that he has found another job (his 3rd since 'they' began) - she is starting to come round and do 'strange' things again. I don't really know if its because of the relationship we have with the kids - or if she can't truly let go. The best thing I have done is extract myself from it all and foucs on my life. If I sit and try to analyze it and try to get into her head, it only drives me crazy - and hits my PMA hard.
In your sit., I would continue the road you are on but pull slowly away..focus on your life. Through your actions show the X that you can and will survive on your own (so to speak). This MAY make her think she wants to be part of your life enough to push her to take action. Just a few thoughts. but I'm not really sure of things myself.
