Family say hateful stuff

How do you deal with close family such as parents who constantly say hateful things to you in front of your children . I was in a bad relationship left went move in with parents to get on my feet and all they do is throw salt in my face about how my ex did me wrong and how he don't do shit for my kids. Sad part I take care of my kids I don't ask them for a penny. I moved on for peace and a better life to hear my parents keep reminding me of ex hurting me. How can I really heal. I lost my job BC of corona virus crisis and have no place to go so I'm stuck in hell again. I'm praying for the crisis to end and get a job and place And never look back. I'm a good person and been hurt all my life by family friends and lovers. I just want peace..... I just want to be happy and my kids happy. Any advice
