AITA for not wanting my husbands toxic mother around any of us anymore?

Hi there! So to give some background my husband and I have been together for 10 years married for 4. We have a 2 year old son who we love very much. We do have our problems that we are working though but the biggest problem we can’t seem to resolve is his mother. His mother is the type of person who doesn’t actually want to be a mother or grandmother just likes to flaunt the titles around to anyone who will listen. From the moment I met her she was a shitty parent and over the years it’s just gotten worse. She’s taken money from him (about $5k) when we were teenagers dating she’d make him stay home when she had her period so he could cater to her every need. The list just goes on. But let’s just discuss the last 2 years in particular. We found out we were pregnant in 2017 and his mother was so happy when we told her and all was well..... for alittle while. When my doctor was getting our medical history my husband admitted that his mother won’t tell him who his father is so he doesn’t know about that history. My doctor advised him to ask his mom about it so she could try to piece a decent record together for the future but no pressure or rush. Fast forward to our gender reveal and she shows up an hour late and leaves as soon as it’s over causes she claims she’s super tired and wants to sleep. She went back to his aunts house and partied the rest of the night thinking we wouldn’t know. But before she left my husband pulled her aside and asked about his dad and she got mad at him and proceeded to yell and berate him for even asking such a thing. After that moment he decided to cut her out of his life. He was really hurt by what she said and did and it only got worse from there. She started back when I was pregnant she wasn’t going to come to the baby shower never gave a reason just stated she wasn’t coming so day of the shower comes and his aunt comes charging in screaming at us asking why her sister (baby’s grandma) wasn’t invited. Apparently she called everyone telling them how awe full we were for not inviting her.

1) she stated long ago she wasn’t coming

And 2) my husband cut her out he didn’t want we there so she didn’t get one.

He cut her out more after that one.

Fast forward to when our son was born we were in the new baby bliss, loving life and loving our new little family. She called us repeatedly on my due date asking if the baby was born. We both ignored her calls and messages. my husband’s older aunt who’s like a true mother to him backed him up and ignored her too. Life was great until someone else in his family told her and sent her photos. From what we have been told when our son was born She proceeded to tell everyone in the family that our son was not her grandson he looked nothing like my husband and that I cheated on him and was tricking him. It’s not true at all. We were told this about a year later.

When my husband was told this information he just shrugged and said I can’t say anything to her about it cause I didn’t hear her say it out loud. This is his logic for a lot of things his mom does and says.

Anyways a couple months after our son was born he let his mother back into his life again. he was sick of family berating him about it all the time so he just gave up. So she’s been in our lives the past 2 years our son has grown but has been in it very little. She lives in Kentucky and never calls simply texts asking for pictures or uses other peoples facebook accounts to get them. When she comes to visit she doesn’t visit long or sometimes won’t even say she’s in town.

Just recently she came into town to go camping with her sister. Told us she was going to come visit before camp and stay for dinner. I said it was fine I planned a big dinner and everything. She showed up an hour late complaining that we wouldn’t let her over sooner (I work overnights and wanted to get some sleep before she came over) she brought my husbands younger cousin along that we didn’t invite or even know was coming. The only reason she came was so his mother could use her as an excuse to leave early.

My MIL stayed with us 2 hours out of her 5 day stay. I was appalled. she claims to love her son and grandson so much and that she’s the worlds best grandma but makes little time to see them! I’m mad cause now my husband is hurt by This but won’t do anything about it. His excuse for her shitty behavior is “well she’s my mom I love her” I understand it completely but I’m at the point where she needs to go. She’s toxic to him and it’s affecting our marriage and honestly I don’t want our son growing up dealing with her toxic traits. She thinks buying him gifts and such will win is affection or something and I’m sick of it. I’m grateful she has bought him some diapers recently and have thanked her for it but I just want to protect my family. She causes nothing but pain for my husband and I don’t want it to go on like this. There a lot more that she has done but it’s way to much for one question.

AITA because I don’t want her around our family?
