5 years ago, I was cheated on.

We have 4 children (1 adult). To this day, I can't be intimate with her. I'm still mad. She's still friends with him.

Yeah, I know - divorce. I know that not divorcing her is teaching my kids how a bad relationship works, but I want both of us present for them.

How do I get... not freedom, but solitude, while still being present for my kids?
