About five years ago I had the same problem with the guy I liked. I used to puke every time I knew I would meet him (first time it happened right in front of him, then I kinda understood the problem and prepared myself before going out the house). But we still got together in the end, and we are a couple to this day. If your crush cares about you just enough, he won't reject you for being sick; if he's so shallow as to change his mind about you for an incident like this, he's not worth stressing about; if he didn't like you before, even without puking you wouldn't have changed his mind. So try not to be too mad about it.

maybe try practicing in front of the mirror and have "scripts" ready for people

I think you ‘projected’ yourself to him in just the right way

Hey, at least you didn’t shit yourself, too (as far as we know), so you’re 50% cooler than that other girl!

Sexy!

I thought that this was just a South Park joke.

Nope, he isn't Mr. Right. Your body activated it's defensive mechanism automatically. Move on now.

One of the pros of being aromantic- I don't have to worry about doing this myself. Except in my case I would probably have a literal heart attack.

That’s gross Stan!
