MLC World, Thanks for checking in. I think you would be wise to distance yourself so you can heal. I won"t tell you i never think about my STBXW but it gets easier the less there in your life when they are in this place. That life doesn't exist any more.
My almost adult son talked to me the other night about his mom. he said Dad"My Mom is dead to me" She may be walking around but she is dead to me.
I mainly listen and validate his feelings and tell him she is your Mom and is in a place in her life thats difficult.
the amazing thing is she will tell her sisters that there relationship has never been better. That shows you the disparity in us as humans when one loses there way in this manner. Things that make you say wow.
I will be there for them. I hope the other two aren"t thinking the same way.
