I'd lose it on her. That's bull. Your her mother not this other woman. And if she isn't mature enough to make her father be a real dad she isn't mature enough to even be a mom let alone I can't believe how rude she is by doing that to you.
Oh hellllllll no.. I'd be pissed she even sent that picture too 🤔😠.. Wow there's only ONE mom and unless she married to him than she'd be step mom but obviously she's overboard with it. Smh
