Son or dog?

My “fiancé” and i are meant to moving to another state and we’ve been meaning to re-home his dog. This has been an on going topic for over 24hrs. “What if i brought him?” When its already been discussed he’s not. His dog is an XL American Bully. It’s destructive, doesn’t listen, wants constant attention, barks if he doesn’t get it, literally bulldozes people, chews and rips everything up. Not a safe dog to be around. I don’t want to go into full details rn but he literally said “ill take (my son) if i will take in his dog”. I replied did you just give me an ultimatum between my son and your dog? Now he’s trying to back track. What the fk is wrong with people? Humans over dogs every day of the week. Sorry but my son comes first. And thats the first time I said that or make him feel insecure about it. I would never compare. I will go into detail later as its late in my country. But what the actual fk did i get myself into. I think I don’t have a fiancé anymore which is fine. Sorry on this instance a child safety always comes first
