MIL wants my daughter at her 50th birthday

My MIL messaged me inviting our family to her 50th birthday. She didnt bother messaging my husband because he tends to leave her on read a lot. She said she would at least like my daughter there for this huge milestone. My husband isn't going. He has complicated feelings towards his mother. But I really don't want to be at my MILs house without him and I have to go if she wants my daughter there because my daughter has autism and is super attached to me and her father so she would have a meltdown at my MILs house.

@Jenee my husband doesn't care if our daughter goes. He's just not going. It's my MIL that wants her there.

Edit: I don't really feel comfortable with being over there with my MIL without my husband. For anyone who needs more backstory and why my husband is very distant with his mom, his mom turned a blind eye to a lot of things. My husband has dissociative identity disorder which is rare but stems from severe repeated trauma before the age of 9. She didn't harm him herself. She just allowed a lot and turned a blind eye to things and still keeps many of these people in her life. She has this toxic positivity to always look at the good in someone no matter what. Her thought process is "Hmm. That person is a pedophile. BUT they gave a dollar to a homeless person once?" She isn't intentionally a bad person. Because of her toxic positivity beliefs she turned a blind eye to many things that happened to a her children and keeps bad people in her life. I just don't ever feel comfortable around her. We have a decent relationship as in she will contact me if her son is ignoring her but that's about it
