Havent heard from my ex since maybe October. Long story short he is a deadbeat, and doesnt have anything to do with our 6 year old since we divorced 5 years ago (had little to do with him since he was born). I texted "merry christmas" on Christmas and never heard back. Since he is in a relationship with a woman who has a 11 year old from a previous relationship, and his own father isn't in the picture, he is this boys "dad", and will be doing Father's day things with him.

Should i txt or call my ExH on Father's day? For my son's sake?
