Ok.

You have 2 options.

Stop making so many harmful assumptions about your partners child. Theirs a good chance he’s just weird and he’ll grow out of it, but you’re not exactly helping here.

Hell, to be honest I was weird as shit as a kid until my dad kicked me out and then I matured real quick.

If I had to guess my issue is that I’m essentially half asleep most of the time unless I have a Red Bull or 2.

Or you can always just leave.

Right now your post reads like ; “This annoying kid is messing up my relationship with his mom, I’m the victim here”

I’d venture to say all kids are annoying and if you can’t deal with that date someone without kids.
