*cough* I'm married to a man 18 years my senior. Sometimes it doesn't work so well -- he'll assume I remember the same things from my childhood that he does, like cartoons and music and fashion, but as he grew up in the 60s and 70s, and I grew up in the 80s and 90s, often there are complete disconnections. I know our relationship working is rare; the first few years we were together, people constantly mentioned failed younger girl-older man relationships to me. But we actually met in college, him as a re-entry student, me as a first year. I think that's why our relationship works: we're in similar places in our lives. In fact, right now I've gone past him, as I'm in graduate school and he's been delayed by his illness and disability. But it's evening out now with his business starting.

Anyway, older guys are great -- if they understand that you're younger, that you're not the same generation, that you might still change. But there are lots of advantages, especially with sex! :P Extra experience pays off.

Though as you say, you fall for them but they don't reciprocate; that can happen to anyone in any relationship at any age. :) As my sister has said, "Every relationship you ever have will be a failure. Except one. Maybe."
