It's slightly weird, but who gives a shit. You have nothing to lose, so might as well give it a shot

If your match expired, it's low probability that she'll remember you so try to go under the radar and start the conversation like you'd normally do.

If she says "Hey, didn't we match on Bumble?" Say "Did I swipe right on you?" And if she says "don't know" or "yes", tell her "Actually I might have... out of politeness"
