Complicated mess

So this might sound a bit over dramatic and nobody probably understands my way of thinking since I been on my own for 2 years. Nobody knows everything..anyways my husbands family hates me. Everytime him and I got into a argument he sends screen shots to his family about what is said. Which is more like people worried about what I said. This has been going on for 2-3 years now. He tells them anytime we get into a argument disagreement whatever it doesn't matter. They know me based upon thru him. I spent time with them while we was engaged and at the beginning of my marriage and some time thereafter. They hate me for any bad shit I've said or didn't do right in their eyes. They are haters. I know they are still his family but this makes it hard on me because we haven't started a family yet and want to. For me it's hard because my kid has to go see people who absolutely hate me. How do I know they won't fill my kids head with stuff in the future? Idk it's more of a mess then I'd like to deal with but for me it's really hard situation plus I deal with my own mental health and for almost the past 3 years I been on my own with this going on and not many people can possibly care. Theres just literally nothing I can do but it's stealing joy and happiness from myself each and everyday because clearly I allowed it to happen. Then again I do have a good heart so it's hard for me to just wipe it clean and forget about people who do not care or lose sleep over it.
