I wanted to add something too, I am older now and was thinking back at where I was at that age and it's around that age that I started my own business. I loved being a mom, but I also wanted to do other things.

Now women are more career oriented too, it's not like the old days where a lot of women were always more stay at home and they built their lives around that which even sometimes included being more of a mother to the husband than having a "play together , growing and learning, sharing that too" relationship.

The more I think about some of the her behaviors that you have described? I really think she definitely doesn't want to EVER go back to the relationship you did have together. She said, "I gave you 10 years". Well, I think what that is really saying is "I want to be more than just that and I want to get educated and be independent and grow in that too". Independent doesn't mean "single" either, it means having a sense of freedom to grow and earn money and "not" depend on the partner so much.
