I don't know how she wronged you, but she has the right to leave you and the right to change her mind on if she wants children. That she left you for money, that's your interpretation, I feel.

Your feelings are confusing to me, though that may just be me. I have been in love twice and while I was, my deepest desire was for them to be as happy as possible. With or without me. I'd push the button to make them fall happily in love with someone else. I'd really do it, no hesitation. I'd be in pain, but I'd proudly bear it.

That you still care for her but want her to be unhappy, that is odd to me. An alien feeling. But I do know your feeling is the norm.
