How to deal with bad behaviour. Help ! ! !?

Hi. I know these things are circumstantial, but I'd still like to ask anyway

I have a friend (I'm male, admittedly, she's female). She's quite playfully, over insulting towards me. I know it's (supposedly) to be not meant, but recently absolutely everything I do is wrong, anything I buy is unfashionable or hideous. If I'm right I'm wrong, and if I'm wrong then I'm in for it double

So what's made me ask this question after about 6 months?

Today I was invited out, and the second I got there I was just completely slaughtered verbally. After an hour I just said I needed to be somewhere, made my excuses and left. It was just horrible (I'm not sure how I'm supposed to sustain a good mood either, I'm allowed my bad days too)

I understand something may be going on in their world, but why ask to meet me then? How do I fix something like this?

I've lost count how many times I've shouted for bills or been nice, it seems to make it worse if anything

Tomorrow she'll probably be nice to me for a bit, but the nasty bitchy side will return

Am I just as much a serial offender in sticking around, as they are dishing it out? Should I just passively retreat in future? Should I continue to rise above it and hope they get better around me?

So confused
