Mother in laws 😡

So unfortunately we still leave with my mother in law because my husband thinks it's best for now 🙄.  I come in from work some family I haven't met were there and how does this woman introduce me?  This is (my husbands name) baby mother.  Not this is his wife or my daughter in law this is his baby mother.  Of course cuz it's his mom and she's old he sees nothing wrong. 😡 is it just me?
