Question

So me, my 3 yr old, and my bd were at the park and some little teenager was arguing with another scrawny teenager. The other teenager threatened to pull out a gun and was walking to his car to get the gun. I told my bd and I said we need to go we have our son here he can’t be around that. He wouldn’t leave. He’s now saying “girl no teenager gonna shoot someone”. He stands on that. Now im just pissed cause he has no fuxking common sense or survival instincts. And now im scared to leave him completely cause I don’t trust him with my son. Idk what to ducking do

He says that’s he read the situation and just “knew”
