Hi Ash,
Has he ever apologized to you for being an ass? Does he “get it”? Does he genuinely feel bad for being disrespectful in the past?
There is a slim chance that he acted that way because he was just a dumb kid at the time. Maybe he has grown.
But, he did blow it, and if he wants a relationship with you, he has to know WHY.
Yes, I have been with a Disrespecting Entity, but he was only able to make that fatal mistake once. Respect all the way now! But take note, ONLY as a FOREVER Friend-Zoned!
Meanwhile, continue to co-parent your son!
Best,
Inky
