I am finally to the point were i do NOT want my MIL in my son life anymore. The fact that she chooses to spend her day off with the very man who has left her multipul times because she wont allow him to have sex with her daughter (my SIL) and is physically, mentally and verbally abusive to her. I am no longer going to reach out to her to see him. If he grows up not wanting to see her not my problem. She was always to preoccupied in that man rather than her only grandson. And whats even more annoying is that when she does see him she tries to make it all about my mom being his favorite grandma... DONE.
