Mother-in-Law Problems

Background: MIL and I were close, but as soon as my son was born, she became obsessed. She constantly buys him things we don’t need or want, and constantly narrates what he’s doing in a shrill, loud voice. She’s fake cried super loud more than once bc she thinks that’s how you’re supposed to teach them emotion. She now seems incapable of adult conversation. There’s some safety issues too and I don’t feel fully comfortable leaving him with her, and definitely not with her driving him anywhere. She tries to take over and do things that are special to us to do for the first time, i.e.-swimming, dyeing eggs for Easter, etc. Anyone else have similar issues?!

My partner has started talking to his mum again and wants to see my daughter. Now I know she will be safe if she see's her but I literally have sooo much anxiety about having her back in our lives (shes very verbally abusive and has been physically abusive to her own niece in the past) Every time he asks me what to do, I cry... he wants his mum in his life but I don't want her in mine or my daughters 😫 What do I do !??

How do I get over her being so indifferent towards my son & my 2nd pregnancy that I now just have no interest whatsoever in her company etc … i feel like it’s too little too late at this point…. 🙄

My 2 year old has always had a close relationship with my mum, they spend a great deal of time together however my partner’s step mum (basically his mum) is not hugely interested in spending time with her especially all together she wants to do stuff 1-1 with my daughter. I gave her the responsibility of collecting my daughter from nursery every other Tuesday on her week off as I needed someone for the Tuesdays anyway. Everything was fine until 6 weeks ago when my daughter was unwell, she screamed at nursery pick up and didn’t want to go with MIL, we assumed it was because she was poorly however it had continued to the point where nursery have raised their concerns with me because they never hear my daughter make noise like she does when grandma picks her up. I’ve tried explaining to MIL that perhaps spending a bit more time with her might help get her used to it etc but she’s just saying “she hates me” all the time. It’s making my partner paranoid that something may have happened to cause this despite the fact he trusts her, he can’t find another explanation which I get. However I also despise the woman (secretly, I’ve never made that apparent to my daughter or my MIL) so I’m thinking is this just my daughter being a good judge of character (oops), had something happened, or is this just a phase that she will snap out of?

So I have this mother in law that kicked me and my children out when they were 1 years old and the other a few months old and when we went back for our kids stuff she had gotten rid of it all....now she is having health problems and apologized through a voicemail and I've been letting my fiance see her just in case she doesn't get better and now she's coming home for Easter and we are doing Easter with her I don't trust her as far as I can throw her but how do I act around her my face would literally give me away lol so how do I be nice in a way that tells her I've got boundaries with myself and my children now I don't trust her but am tolerating her just for my fiance????........Does any of this make sense???
