i just found out yesterday that my dad has been cheating on his wife (my mom) for the past 5 years of their marriage. I'm not sure what to do. i love my dad, i always will. this doesn't stop him from being my daddy, but i feel betrayed. just as my mom does. she's been with him longer than shes been without him. they've been together for 20 years! she looks so lost and i dont know how to help her... i dont even know how to myself.. has anyone else been through this? does anyone on here have any advice?
