I found out last week that my dad had cheated on my mum. He claims he’s ended it and not seeing this other woman anymore. He begged me not to tell my mum and he offered to buy me a car if I didn’t tell. I said I’d think about it. He showed me messages confirming he’d stopped seeing this woman, but he could just be pretending. Part of me wanted to tell my mum but I also know it would hurt her a lot and probably split up our family so I’ve said I wont say anything. I’ve told my dad he has to get tested and I’ve accepted his offer for a car and said I’ll forget it happened. 

AITA for not telling my mum?
