I need some insights and advice.

Hi! what would u do if u know that ur father has a mistress sa abroad (well-known na siya actually, 2 years ago pa) and recently, after having a hunch na may kabit din ang mom mo, bits by bits, u have an evidence of her cheating? napapansin ko na after the incident sa dad ko, nabawi na siya and nakikita ko talaga ‘yung effort and want niya sa pagbawi kay mama. but my mom don't want to accept it. kaya pala nung time na sinabi ko na affected ako, she said na “ti’gnan mo ako, hindi affected” kasi pala may kabit na rin siya hahashha
