Would you cut off your husbands mom if she...? Thank you so much if you read all of this I need help

So she was never there for my husband. She divorced his father when he was around 10 years old. It was hard on him because she really didn’t try to talk to him or be in his life at all after she left. She was an alcoholic and I think she also did drugs and abandoned him. She took all of his fathers money and they were pretty much homeless for a year.

Anyways. Years and years go by and he had and still has a lot of resentment towards her. Me and him start dating at the age of 22 and find out I’m pregnant at 23. I say that he should give her another chance to be involved and maybe she has changed ( she was sober for around 10 years now and works for the state so she seemed stable ) So eventually he did. She started coming around my whole pregnancy and was very nice and helpful most of the time. I had moments where she bothered me for example she pretty much forced herself coming to the hospital the morning I was induced. Literally followed us there and then when I needed my husband and was terrified she wouldn’t stop trying to converse with him and kept being like hurry up baby!! And it pissed me off lol.

Anyways still not a huge deal.

She really cared about our baby and kept coming to see him and helped us with him once a week a few times to let us sleep for a few hours. Then when our baby was around 6 months old , it was Mother’s Day and she cane over ( we were very broke living with my father to try and save money) and brought me a gift I said thank u so much we spent. A little time together and she left. She then calls my husband and tells him that she’s hurt because she was expecting a gift ....I was in shock. She had just came back into his life and he was trying very hard to let things go and she was very rude about it. He still let it go and said okay sorry.

Then we were going to get married a month later (just signing papers and having a bbq) and I texted her and said okay were doing it in a week. Only have 1 or 2 people there for witnesses and eventually we are going to have a reception after covid. She was pissed and said well I’m moving this weekend and I need him (my husband) to help. So I said okay I will literally change our marriage date to the next day then. She then calls my husband hysterical saying that whatever it’s fine and that I had told her he couldn’t help her now and all of these lies and trying to make him feel bad. It pissed me off so bad that I was crying. I still let it go.

Then me and my husband got in an argument months later and I didn’t reply to her for a few days. So she texts my father and said she’s worried about mine and my sons safety?! Acting like my husband is qbusive ?!!!!! Then my dad has all these questions that I’m telling him she is crwzy and I have no idea what she is even talking whout. At this point my husband is livid. He texts her and says he wants to nothing to do with her and he can not believe she would act like we are not safe with him and he is done trying to continue a relationship with her. And blocked her. She then will not stop texting me. A few months go by and I tell her it was not okay that she did that she apologizes and says it’s because my husbands dad was abusive verbally to her. We still don’t talk for another few months. Me and my husband have a talk and decide to let her see our son and give it another try for our son. She comes over with Christmas presents and is being super awkward and weird and it was so uncomfortable. My husband and her talk and he tells her that it wasn’t okay and he is not going to deal with that or anyone acting like he is abusive to us. She then gets all upset and is like ok I should go and leaves super quick (my husband said u don’t have to leave , said love you and tried to give her a hug) she didn’t say it back and left. Then texted me and said sorry my son is such an asshole he’s too much like his father , next time we can meet him without him there.

I did not respond and I am so pissed. I want nothing to do with her. Is that justified ???? I don’t think this is normal at all

Edit - sorry I meant to add that it has a been a few weeks since she texted me that and won’t stop texting me every few days and then said I’m concerned about u since u are not replying. So I said why are u concerned about me ? I do not like that you text me calling him names and putting me in a very uncomfortable position. He didn’t deserve that. She said ok well i already said sorry won’t happen again. Then I did not reply
