Mother in law

So a few weeks ago my husband and his mom got into some argument and asked me to smooth things over for him comfort her etc.. it was an argument that was he disrespecting his aunt and the mom felt embarrassed. So I did my wifely/ daughter in law duties because it’s the right thing to do. Now my husband disrespected me in FRONT of his mom calls me cunt white garbage gets up to intimidate me I guess and what does she do???? Stands there and stays by his side. The following morning (she lives on the bottom floor of the house) she doesn’t even come to check and see how I’m doing I get that’s her son but it’s like I have no support in this house and this isn’t the first time It’s happened. I told them both last night I have no support here I’m by myself and my husbands response was go “F” yourself again in front of his mom.
