Girl's Behavior

I feel like my friend plays dumb for me to do things for her?

We’re both 24 f. My friend will get in my car that she’s been in 100x and ask me to turn her seat warmer on and acts like she can’t do it herself. She did this yet again and I make a comment saying how it’s the same as her car and she giggled like she knew what she was doing. I’ve noticed she does get jealous of me (ex: I’m white and like black guys and she’s said she doesn’t find them attractive bc it’s not her type. I start talking to my ex again all the sudden she finds black men attractive. Not saying she can’t but the timing isn’t a coincidence…) and says shady things to try and put me down. When we go out to a bar, out of nowhere she’ll bring up personal issues from the past in front of men to try and make me look bad and when I say something that contradicts her she’ll giggle. She FaceTimed me when she was at target and when she walked by girls she asked me about an infection I had that was already done and over with like 4 months prior. Why is she like this? Is it worth ending a long friendship over?
