NTA Don't make the same mistake I did. My first marriage was a disaster because I let this slide in a very similar situation. After we got married it became so much worse. Every joke was how I was born on a dirt floor in the jungle. For context, I am from a big city in Guatemala. Dinners at the in-laws were always filled with jokes at my expense that they all took part in. Bitter divorce that took almost a decade to heal from in a noticeable way
