I had hurt her deeply by putting our family in such bad financial trouble.
That's b.s. and I'm sure you know it. You can indicate you are sorry she feels that way, but you don't have to feel bad if you tried to make ends meet and didn't. I guess you could work on being more fiscally responsible, if that was one of your problems. Personally, I'd be extremely leery of wanting a spouse whose primary concern is financial. How does divorce fix that? Makes it sound like she wants a sugar daddy.
You handled the talk well though. That was really good. Glad you could be there for her.
