* tell her to tell him or I would and show him the proof.*

This would be an easy one for me, I'd beat the shit out of my mom and make her tell my dad. Sorry if that sounded harsh. Lol I'm a total 100% daddy's girl, my mom doesn't deserve him at all. So yes that's exactly what I would do. But the more sense able side would tell me, to tell him, or else I will and show him the proof.

oh she knows @baltimorebatmom

Have you pulled her to the side and talked to her yet or does she not know you suspect it
