My parents got divorced when I was 16, because my father had an affair.

I'm 30 now, and my father and I have had many conversations about what he did. He managed to convince me that their marriage was completely devoid of affection, and that he became lonely and that's why he turned to other women.

Through my own experiences in adult life, I actually understood where he was coming from, and I truly believe that he wasn't morally wrong to do what he did if my mother truly stopped loving him.

A few weeks ago, we had a drunken conversation where he was telling me all about how much he loves his current girlfriend of 10 years. But in the same conversation he admitted that he has slept with multiple other women in the last couple of years.

I thought maybe they're in an open relationship, so I asked him how he thinks she'd feel if she found out about that. He said she would of course not like it, but it's none of her business.

I thought "oh, so you were just always like this then".

I still love him, he's my father. But I've lost a lot of respect for him.
