AIO to my EX Bf verbally attacking about my son

Reposting this because I posted it out of order last night and received lots of confusion. - sorry new to Reddit

Basically my now ex bf and me got in verbal argument because of my sons lack of direction. He wanted to discuss the military with him.i wasn’t in the mood to have the conversation last night. I wanted to talk to him in person on Friday about approaching the topic. He flipped out. Insulted me. Insulted my son and even my ex husband who is now deceased.
