How will my exgirlfriend react if I killed myself? Would she blame herself? Would she feel guilty and be haunted for the rest of her life?

doesn't matter
you wont be around to see it

She wouldn't care and she would be sucking her new boyfriend's cock while you are eaten by bugs in your grave.

She will care OP now go and kill yourself

She'd forget about it in a few months, a year at the most.

this

I saw george lucas in the CVS parking lot yesterday, that man is everywhere

Yeah it would definitely be a great way to get back at her for whatever, you should do it.
Trust me I'm a doctor

No, she's a woman, women are incapable of sympathy. The only reason they even console babies is because they can't stand their crying. They are also incapable of feeling guilt. Instead they post-fact rationalize to the point of always being the victim/winner of every situation in their whole lives.

She will fake care but be fucking Chad on the day of your funeral.

Kill her instead
