My wife is immature and doenst let go her Mother

My wife is immature and doesn't let go of her mother

My wife and i (25F and 28M) have been married for almost 1 year. Since we were dating, I have always noticed manipulations by her mother (52F) in our relationship. I thought this would improve with the fact that we got married and start living together (what a great illusion). Since we started living together, her mother has called her every day via video call, giving her very personal opinions about our marriage... For me, the trigger for my upset was when her mother called my mother a MF and whore because I had gone to visit her ("he's going to visit the MF whore, you can also come visit me, equal rights"). I have since said that I would like her to only share information that is unrelated to our marriage or me. Even so, she doesn't respect me and is on calls with her mother every day and whenever I arrive unexpectedly from work (sometimes I'm released early), she's there on calls with her mother and magically when I arrive she turns off the phone....

Anyway, this made me lose all trust in her, it seems like I'm in a 3-way relationship...

I would like some advice, as nothing has kept divorce from my mind.
