Am I in the wrong?

My post history has a lot of details but suffice to say, I do not like my MIL. I do not want her near my children unsupervised because she described her weird breastfeeding fantasy to me while I was pregnant last year and told me she always wanted to breastfeed the babies she watches and when told how inappropriate that was and how pissed I would be if someone did that, she said “well I wouldn’t mind. If I could find a way to lactate I would.” I no longer think she’s just a harmless dummy who doesn’t think before she does and says things. I think she’s genuinely deranged and would molest my children if she could.

Onto this weekend. My grandmother passed. My mil , apparently, was very fond of her? They met once a year at most for the past 7 years for my daughter’s birthday parties. And my mil would sit and talk to her for a little at these parties. So when she passed and my husband informed them she called me. It was the day before the wake and I never answer her phone calls so I let it go to voicemail. She left me a 40 second message with condolences and letting me know she would be attending all the events including the church and repasse.

I did NOT invite her to these things because I didn’t want to spend the entire time fighting her off my baby when I am supposed to be grieving the loss of my grandmother with my family. She also has a tendency to hyer obsess about the children and hover over them trying to get them to give her full attention the entire time she’s with us. Essentially making my grandmother’s wake her personal playdate.

So I texted her a message in reply as follows
Hi (mil). I got your message, thanks for the condolences. You don’t need to come to the church it will be very busy and we will be with my family.

She didn’t reply to this message and when she showed up to the wake she ignored me and looked very angry. My baby ignored her which seemed to make her even angrier. She then proceeded to sit with her husband in the second row of the funeral home while the priest was giving his eulogy essentially taking up the space for family leaving no where to sit for my uncle (son of deceased ) and cousins which is so apropos for her thinking she’s more important than she is. I was SO glad I told her not to come but it was very clear she was furious with me and she gave me an attitude as she was saying goodbye and told me “good luck with everything tomorrow”. I do not know how to interpret this statement but it was a very odd thing to say to a greiving person. My husband said I’m overthinking it and she probably just tripped over her words. He’s always making excuses for her but I think she’s very passive aggressive and always has a meaning behind what she says.

Was I even in the right to tell her she couldnt come? I got mixed reviews from my family. Some said you can’t tell people not to show up to the funeral etc but I feel I did the right thing. She doesn’t really belong there and I could tell she was only coming to get access to my kids .
