Husband talking to his mom again

Okay so idk how to deal with this. I’ve been married for 3 years. Dating for 6. When we met, his mom was his best friend. I mean.. they were SO close it was crazy. She immediately didn’t like me because she felt like I was “taking him away” when in reality, he was just growing up.

Anyways, she began to hate me and talk bad about me, anything to end our relationship. She would get into his head and make him question us. I had multiple miscarriages after the first year of our relationship and she said how happy she was about it. How it was such a good thing.

We welcomed our daughter in 2016. She’s met her like 5 times and she’s 3 now. We also have a son who is 11 months old and she’s never even seen a picture of him.

He’s the big thing. We had another daughter who passed away. The day she died.. in my arms. My husband called her crying and screaming from the back of the police car (sherif drove him to the hospital) she had no sympathy.

She didn’t ask to come to the funeral (probably because she hated me)

1 year after her death we went over there one day for a visit, which was the last time we ever went there. Apparently a picture of her that I had in my wallet had fallen out and she gave it to me and said straight to my face “until I seen this picture, I didn’t believe she was even real. I thought you guys made it up” and never even apologized for that. Then I found out that a week after she died, she called my mom saying that we lied about her death and she wasn’t real. Which of course my mom told her she was a fucking idiot because my mom went to the funeral.

There’s a lot of other incidents, she is a manipulative person who doesn’t care about anyone. She didn’t even come to our wedding because he married me and she hates me. But it’s been over a year since he has talked to his mom. And recently he told me that he won’t spend the rest of his life without his mom. That if he has to leave me to be able to talk to her he will because that’s his mom..

I get it but at the same time.. I can’t let that back into my life. She has made me cry every single time I’ve seen her. Made my husband cry so many times, told me that my daughter (3 year old) should have never been born. Laughed when she found out I was raped. So I told

Him that he will have to leave me.

Idk where we stand. Am I wrong? Is he wrong? How do we get past this? He’s going through what seems like depression and feels alone and I think that’s why he wants to talk to her and he’s holding on to all the good times with her. I need help.
