Hi--I'm a little older than that--think about how you changed between 15 and 25, and that's how much people change between 25 and 35. Maybe one of the things you realized as you grew older is that intellectually she wasn't where you wanted her to be. But you're changing, it sounds like she's changing, and trying, and there's a lot to be said for that. If you're both on the same page maybe you still can build a good life together within the marriage--but maybe your intellectual discussions about world events happen outside the marriage?
