Having to ✂ family off while pregnant

I have recently needed to make the decision as to if I would stop speaking to my mother in law for a VERY LONG TIME. She been very kind to me through buying maternity clothes and wanting to buy the baby's stuff (she hasn't yet). But everytime I see her, she feels the need to call me fat. I don't appreciate it at all, plus it's just rude as fuck to say to a pregnant woman. I was 128lbs before my pregnancy began, and I am 150lbs now and I will be 6 months pregnant next Friday. She will pinch my cheeks and talk about how fat I am. All that. Plus we do not have tested greatest history and I only tried to make up with her recently for her to see this child, and our first son. Not anymore.
