I thought me and his mom was cool...

So I cursed my boyfriend babymama out for being petty. His mom sent him a long voicemail saying how I’m using him and I only help because I need somewhere to say how he needs to wake up and smell the coffee... she said I need to be kicked tf out for disrespecting the mother of his kids. We all know babymamas are BITTER & be doing too much. I thought his mom liked me. She said “ I’m getting tired of your dumb ass chick “. Any thoughts on this? She usually comes over Sunday which is tomorrow .. she knows I cursed his bm out because the bm calls her I guess.
