I would look for a way to get away from my in-laws because being in a house full of complaints and abuse is the worst, I think no woman deserves it, I do not want my son to grow up in a place like that, you have to have the courage to face that kind of experiences...
I wouldn't allow my child to grow up in this environment, the father is a poor role model and I could point to other relatives and friends that set a better example.
