bps,
My mother and father went thru a bitter divorce when i was very young, they hated each other with a passion, my mom did things just like what your ex is doing. my mother would go out of her way to throw my dad under the bus. anything i didnt have or get to do was always his fault, even though she wouldnt work in a dang pie factory as a taster. she would not let my dad visit or spend time with us. The only way I knew my Dad loved me is I would see that check from the clerk every month. im 43 yrs old now and im very close to my dad, and the only time i hear from my mom is when she wants something. If that tells you anything. Fight , fight ,fight for your son he needs you in his life, believe me.
