Can someone explain why men will flirt with a woman, suddenly back off and then act nervous around them?

This keeps happening to me and it’s really confusing. I totally get that people don’t always mean it when they flirt or at least change their minds, and I now assume they’re not being serious but to then act nervously around me doesn’t make any sense? It often involves them noticing me, staring at me furtively when they think I can’t see them and then appearing all serious and behaving as if they haven’t seen me, when they think I am looking at them! It’s really confusing.

It’s often guys I only know in passing, that I’m not friends with etc., but it honestly feels as if they’re scared of me which makes me feel horrible as I’m a genuinely kind, fun person who smiles a lot and will talk to anyone! I’d hate to think I’m randomly going around making people feel bad. Is it that guys think all women will be nasty if they no longer flirt with them, because that seems mad to me?

Or am I genuinely making them scared of me?
