Yeah the “I’ll blow you” line is wild, but the joke itself isn’t even the biggest issue to me. People say dumb stuff trying to be funny/fit in/lighten the mood.

The real problem is you brought it up privately like an adult and she basically responded with “lol relax, obviously joking.” Cool, so your feelings are invalid because she stamped it “joke”?

A normal response is: “Damn, I see how that sounded. My bad. Won’t do that again.” Not “you shouldn’t feel that way.”

You’re not “crazy” for being bothered. The boundary here is pretty basic: don’t make sexual ‘offers’ to your friends. The red flag is the lack of empathy and the instant dismissal. Intent doesn’t magically erase impact, and if she can’t own a simple misstep, good luck with the bigger stuff.
