Is my husband gaslighting me?

My husband and I almost got a divorce because he yelled at me and called me names infront of my mum and dad while I was holding our 6 month old baby His mum called me as apparently he had rocked up to her house banging on the door and being all angry and I told her what happened and my mum also said “he called my daughter a b**tch” and I can’t stand for that, it’s not ok - we don’t speak like that in our family Eventually things were ironed out but my mother in law is fabricating a bullshit story and saying that my mum called her separately and said something about my MILs dead husband etc etc My husband went to the extent of taking screenshots of a call log between my mum and MIL days before we had the fight and said that my mother and I are liars… I asked him to look back at his messages and he realised that this call log was not after our fight where we almost divorced and he was proved wrong Instead of taking my side and saying ok this didn’t happen - he is verhemently backing his mum He doesn’t see the problem that he is choosing his mums word over mine and is saying I am shit Should I leave?
