never give up bro, i know at least for me cali is a mother favored state, I have spent 40k in court only to be awarded 49.99%, with character letters from police and city council , doctors etc they don't care, half the time the judge doesn't read the character letters.
she disobeys court orders and visitation constantly and dares me to bring her back to court
your son will return to you brother, I am sure you planted excellent seeds, but please never give up, send him little positivity quotes anything you can in the interim to keep his mind in the right place
hearing shit like this makes me tear up. I was that kid who needed his dad around. My life would have taken a far different course. I have made peace with my bio dad in adult life, he's a multi millionaire, has a grandson (my son), and still doesn't give a flying fuck, and he only lives 30 min away, no birthday calls nothing to my son, at least DO OVER with my son that was my only wish for him, but hoping is a fools errand!
best wishes
