JustnoMIL: where do I go from here?

I posted about a week ago about a big (really stupid fight) about them wanting me to pay for a taxi home which would’ve got me home similar time to if I’d just got a train

It’s been tense since, both MIL and FIL have been on at my husband that I was in the wrong as a result they’ll never help us midweek again apparently

They’ve picked a fight that whilst I’m on nights this weekend, my husband isn’t going to their house on a whim because that’d mean I don’t see my son for three days.

They’re arguing because I’m going away for one night at the end of may without my son its selfish of me to prefer To see my child when on the afternoons between nights

And honestly I’m just so ready to cancel everything we have booked in, they’d originally agreed to childcare for my night away in May (husband working) but I’m probably going to end up asking my parents to do it

We’re meant to be at there’s over Easter from Good Friday to Sunday but I just don’t want too anymore

We have a group chat and whilst I’ve responded to direct messages at me, I can’t be bothered on up keeping the relationship

My husband has been sticking up for me the entire time he has said it’s better for our son if he sees me this weekend rather than three days without me, he stuck up for over the stupid taxi argument but he doesn’t want to cut them out

I just don’t know where to go from Here
