Toxic In-law family... need advice!

So does anyone else have a horribly toxic relationship with your husband/baby’s fathers side of the family?

What do you do about your kids visiting them?

I mean these people are horrible! There’s alcohol abuse, openly talking negative about myself as a mother when my kids are around, and they constantly encourage my husband to divorce me. (My husband and I do have a rocky marriage and he had been abusive in the past so when I did call the cops on him his family freaked out calling me a psychotic liar and there was even video proof of the abuse and they think I falsified it, but my husband and I have tried really hard to work through it after being separated for a year)

Anyways these people are awful. His dad is overly touchy with the little girls of the family ( I have a two year old daughter) but everyone just thinks it’s cute and showing love. My daughter met his family once when she was a few months old and my 8 month old son has never met them. My husband was against his family being around but soon as our marriage gets tough he is now all for pushing these strangers who never made an effort for my kids to start being around.

Needing help! I’m lost and so worried that toxic environment will get my kids emotionally or physically hurt.

Additional note* his family is very full of mental health and substance abuse issues and the other kids are not taken care of, frequent injuries as poor behavior for their ages and poor nutrition
