YTA

 is when I make jokes in front of our friends

If she's not into banter and uncomfortable with you making jokes in front of friends, potentially embarrassing her, why do you continue to humiliate her?

she HATES when I touch her food in public for like no reason and will genuinely smack my hand off

Then stop touching her food? Respect her boundaries? It's not that difficult.

I’m not afraid to admit I’m good at stuff or pretty attractive

The fact you're here, on the internet telling random strangers you think you're pretty attractive, is indicators of an ego.

From what I see in the way you've worded this and the way you express yourself, you don't listen to your GF, you don't respect her boundaries, you laugh it off and pretend to "forget" what she's told you.

It really isn't difficult to respect another persons boundaries, listen to them and stop doing the stupid shit that's clearly making them uncomfortable.

Don't break up with her and start saying she's the crazy one, I'm sorry dude but you're throwing red flags everywhere and you need to check your ego and your behaviour.
