Long story. Aita for being fed up with my in laws and being happy they are threatening not to come to my wedding?

It started 2 years ago when my partner and I fell pregnant. We very much were trying as I 31f and he 36m were ready to start a family we started building our house then second COVID and the housing crisis hit. We moved in with my bil. We lived there three months and he was awful, when we told him we were expecting he kicked us out to not ruin his bachelor lifestyle. We moved in with mil. This is where is starts. I worked till 38 weeks, I had bad Edema and was meant to be on bed rest since 4 months but I have an office job so figured it was very similar as long as I take care of my stress and put my feet up I'll be ok. At 38 weeks my face collapsed. Literally. I thought I had a stroke. It was bells palsy but it was bad. I had so much pain. I couldn't eat, water and drink spilled from my mouth it was awful and I was told I may never look the same again so I was in mourning. I was placed on actual bed rest and told to not move. Cut to three days later when I felt like I was going crazy and needed to move so I cleaned a spare room my mil gave to us for the baby. I then went to lay down. I was so happy I told my partner I was so proud I wasn't crying and I did something useful. He gets home and hour later and in the bedroom I suddenly hear yelling. My mil in law is calling me a lazy cow, that I should of cleaned more and that I was milking it and nothing was wrong with me. I packed a bag and left. Mind you I have multiple chronic health conditions for which she knows about and thinks I'm faking such as chronic fatigue and migraines to name a few. I forgive her after a discussion and move back in. After my son is born she constantly is negging me. Telling me I should bottle feed cause I'm not making enough because my son looks hungry. She forced alcohol in him when I went to shower because he was "teething' he was 4 months and not teething. She then insulted me yet again and consistently crossed my boundaries. I never spoke against her but it all came to a head two weekends ago. A year ago I got engaged. We just got into our house three years after building. We had to refinance to afford to get married. Around the time we moved in my bil got engaged. We told them all we were planning April 26. I was forced to go to their engagement party and was again treated like a door mat, my partner was called up with my bil sister to be for a family photo while I was forced to sit there smiling and watching Infront of everyone, my mil told me to shut the fuck up cause my partner couldn't think of a song he wanted because I was talking and when I was introduced to people along side my sil she was introduced as sil and I was a mumbled girlfriend. We have been engaged a year at this point and together 6 years with an almost 2yo. But alright pop off. I decided I had finally had enough of being treated like shit and ordered myself a uber and left.

Cut three days after, my partner and I had been fighting ever since. I said I was sick of him not standing up for me. He said he does in private but doesn't like making a scene. He never has in front of me but says that he doesn't donthat because it would make me feel awkward. Whatever. I tell him and my therapist I've had it. I will see them at Xmas and holidays and nothing else. They have been so awful to me while I never say shit. I am always respectful and polite. They hate me and I have no idea why. But I'm done. So cut to Wednesday after the engagement party. My bil said he can't come to our wedding in april cause they have another wedding in NZ. We then moved the date to August 21/28th if the venue allowed. We were told my bil would not come because they wanted the 28th. They are both in their early 20s with good FIFO jobs and no kids. They can move. I was asked if I would do the 21st by my partner I said ok if the venue allowed. They did.

My partner then posted in his family chat good news we are on for the 21st so no worries. He then got a call that I didnt hear. He was FIFO at the time. That his parents called and yelled at him for moving the wedding and that we were doing it so bil couldn't come and that none of them would now be attending. My partner is upset. I am not to say the least. But we moved our wedding twice to accommodate these ass hats. So now I'm done. I'm done being a doormat and I won't be moving shit again for them so Reddit. Aitha for being sick of treated like this by my in laws and what do I do from here? My partner is not a confrontational man and I know he sounds spineless and I will agree with that but other than my in laws he's a good man. I wouldnt be with him otherwise.
