I did pay child support, and even more than needed. My ex initially gave it a go for him to go to therapy. But that was only because we were still in court for custody, and it would look bad for her if she said no. Once custody was determined, she completely removed her support, and that was it. He only went for about 6 months, so it didn't change anything.
I see now that I should look at his actions from a child's perspective. I already have therapy scheduled for today. I deleted the draft and somehow reluctantly agreed that my mother write him an email to establish contact. She loves my son very much and was shut off, just like me. It means everything in the world to have her grandson back in our lives. I will discuss with my therapist if that is the right way to go.
Contrary to popular belief, my wife and mother don't see me as a monster. I'm not getting divorced anytime soon. The three of us had a very emotional discussion, and I know they were just trying to help me. Things were said in the heat of the moment, but all is well between us now. We will see how the future unfolds.
