I don' t understand their way of thinking but my XH did similar. In his mind, he left ME. Nobody else but me. Our kids, living here with me weren' t left behind, just ME.. And yes, he wants us to be best of friends even after threatening me and intimidating me !! Everytime he loses control of his anger, he cries and works his way of thinking to beleive i deserved his treatment..
Son15 has moved in with him and OW last fall. XH had a business trip and asked my sister to look after my son for a week.. Shouldn' t i known about this ? Do i have a say?I to was upset at XH and also my sister. I do understand that she did it for son but i felt like they came through for XH.

My son' s choice re-opened doors for arguements and spew from XH to the point that son stood up for me last week-end and will now be moving back home after the school year. ( mid june ).

On another hand, i am doing the opposite with my brother' s separation.. He is also in MLC and has left his wife of 29 yrs for OW. he is now at OW3. I kept contact with Xsil. We are friend on fb and we call eachother frequently. We help eachother through this. Am i hurting my brother? He never said a thing nor asked if we still kept intouch but i am sure he knows. Our brother-sister relationship is still very close but his OW i respect but i keep my distance.
So, 2 sides of the medal on my part..
