I bumped on my dad on my campus. I later found out he is dating a course mate in school. I could have easily told my mom but the problem also is that, last year i borrowed my moms phone and notice some amorous text messages between her and a certain number. I didnt confront her because i feel its not my business but uncovering what i know about my dad has put me in a fix and scared to even tell my sister. Maybe they are in an open marriage
