Mother in law advice

I had a good relationship with my MIL until my baby shower in June. Some history, my husband was adopted by her at an older age so it isn’t the most conventional mother son relationship. We would visit his family every other month or so. Until my baby shower. She told him I didn’t pay enough attention to her and sent him some very rude messages. Then when we didn’t allow anyone in the delivery room she said some horrible things to him via message and didn’t even come to the hospital until late the night my daughter was born...basically for a picture with her for FB. NOW...she hasn’t texted or called me at all since June. We HATE going to her house because she has always been a hoarder but it’s gotten bad and there’s roaches everywhere. As soon as you walk in her house it just smells. I’m not exaggerating...hoarders...like the tv show bad. I do NOT want to bring my 6month old in that environment. I don’t want anything to do with my MIL anymore. She’s literally seen my daughter 3 times since birth and it’s not for a lack of us inviting her over or trying to visit...she always has an excuse. So for Christmas she wanted to have Christmas Day and I said no, absolutely not she does not deserve to be with our daughter on Christmas vs my family who helps us out weekly. ADVICE. I’m to the point I am no longer holding back and keeping quiet. I am DONE. And so is my husband but he’s a lot nicer than me. He still wants a relationship with his grandma who unfortunate loves with my MIL.
