So she understands, Diana.
My presumptions here:
She's struggling herself right now for a myriad of reasons. Without putting too much effort into it, possibilities include:
- She's potentially projecting J's death and the probabilities that she could have pushed VR in a similar direction. She may want/need to know how close she came to doing that to him. He can tell her, Yes/No, but reading this will give her a better idea of where he was at, for various points in time post d-day.
- She's potentially feeling a TON of guilt over J's death. What if I'd been a better person and not cheated on VR and accepted Gina's cheerleading? What if I was a stronger person and got her to quit cheating? Maybe J's still alive if I was a better person?
- Watching VR struggle. If she can't understand why/how/etc what he's going through, how can she feel comfortable her kid will grow up with a Dad?
And again, although they're not married, and not likely to be again, his ultimate end goal here should be to be friends with his ex. She can't get unfucked. She can't undo any of it. It's done. BUT, they're tied together for the rest of their lives for that kiddo. Both of their lives will be immeasurably better, if they're on the same page and can manage to enjoy each other's company. Some of that starts with understanding. If you don't know what a puzzle looks like because you don't have the picture on the box, it's awful difficult to put together. While, typically, that's the betrayed spouse trying to put together the picture of what happened in their life, it can certainly go the other way for the betrayer to understand what the betrayed went through. They didn't feel it. They don't truly know.
Edit: Also, VR has shown himself to be an incredibly pragmatic guy. He has a reason. It's certain to be well thought out. Maybe he'll share why, maybe not. That's up to him. But, I'm certain he's spent the requisite amount of time thinking through his pros and cons. It's who he is.
