She sent a text this morning. Apparently, he spent last night at his gramdma's house. Don't know why but I suspect my W is out of town for work. I was able to talk to my S this AM and it was great!
I'm really just about done with her. Emotionally, this still hurts but she's going to do what she's going to do and I can't stop her. All I can do at this point is preserve my relationship with my son and protect myself financially.
