I'm devastated! I just found out today: in full details: my dad's been cheating on my mom. He's been seeing his ex-wife in California, and he's been secretly planning to run away and re-marry her. Me and my mom have been set up! His ex-wife didn't even know me and my mom existed until my mom called her. Even his ex-wife (and her 17-year-old daughter) are just as devastated about this whole issue as me and my mom are.
