Am i overreacting for calling out “jokes” from a former fwb?

So i recently reconnected with an old fwb/ex, i’m a (21M) she’s (22F) ever since we started talking again i noticed she got a bit of a cheeky joke to her every now and then, she first accused me of trying to fall in love with her again, later we spoke about how she's lonely so i opened up to her and told her i go for walks which she laughed and called it "sad and pathetic" (lol) since then she's used it to make fun of me calling it the walk of shame, and i told her i took my braids out (I'm black) (she's white)-if this is relevant, she says it my braids were didn’t look good unprovoked, then today we were talking about selling clothes on an app which we both do, she said…"You should buy from me, maybe a crop top, it would fit your personality" it got to me ngl, i told her she wasn't funny then i ignored her response for day, i later told her, "i didnt start talking to you again to get made fun of" mind you she was never this disrespectful towards me, now im ignoring her and i wanna know if im overacting? for more context she left me cus she was still inlove with someone else
