Well only thing I would say, 10 years is not a big age difference, if she was 32 and you 42. Emotionally, she probably would have caught up with you and may want the same things.
However, 22 is quite different. At that age, most people are still finding their feet in life and looking to explore lots of new things, not necessarily settling down to marriage and children.
When I think about how I was at 22, the things I wanted then, are completely different to what I want now or even my general outlook on life. Saying that, everyone is different.
