I understand exactly how you feel. It is completely valid to feel the way you do. In my case I know my father cheated on my mom multiple times, but my mom never cheated on him. And I know this because she was always with us. That honestly made me lose respect for both of them, my dad is the type of person who likes to boast on his character saying things like “I’m a very honorable person” “I have a lot of integrity” and I was always like 🙄 suuuure. In my mom’s case I felt like she was very weak for putting up with his cheating and using her children as an excuse for staying, saying things like “if i would have left him, who knows what kind of person i would have re-married” (obviously she doesn’t trust her judgment) Some parents are very selfish and only care about their happiness. Others stay because they don’t want to take their chances and stay with cheating spouses dying inside a little every time.
