In laws will be the end of my marriage

It’s been 19 months so it’s not a new problem by any means. My husband is very close to his parents and I can’t stand them and I’m expected to spend a lot more time with them than I want. I already see them 1-2 times a week. Most of the time it’s once a week during the weekend and every now and then there will be something during the week as well. They are also our childcare for the moment so they see their grandson every single weekday.

We had a huge fight yesterday because he said he wanted to have dinner with his parents since he hasn’t seen them in a while (last time was monday and this is not including the daily drop offs and pickups where they chat for a bit each time) and I said we have a full day tomorrow (with his parents) so I’d rather just stay in today and I asked if he’s going to bring our son back first because I’m don’t work early and would like to chill with him (I don’t drive and it’s the dead of winter here so he’d need to do the pick up) Eventually, this turned into a fight. He said it’s so awkward that he’s going to go pick up our son then bring him to me then go back to chill with his parents and that it shows that we (I) don’t want to chill with them. And that it was the perfect opportunity for us to go and have dinner with his parents because we didn’t have any plans anyway. In reality, he would have brought our son back at 3 pm and gone to his parents at 6 pm for dinner so I don’t see the awkward aspect he’s talking about.

Am I in the wrong here for not wanting to chill with my in laws 3 times this week?! I honestly cannot continue this relationship anymore and we talked about separation for the first time yesterday but I need to know if I’m being unreasonable.

Edited to add: my parents visit for one month in the year and stay with us and he told me when they come he is going to apply the same rule that I do where he’ll only see them 1-2 times a week so they are not allowed to stay with us.

Edit: it’s funny how from some of the comments you can spot right away those who are insufferable overbearing in laws themselves!

Edit: I couldn’t reply to every single person who commented but thank you to ALL! All different perspectives were good to hear and has helped me in this mess I’m in :)
