My husband is 21 years older than me. It doesn't really affect anything in our relationship. I think having an idealised image of the 'perfect' partner isn't helpful though as it is a fantasy and doesn't really exist. I'd have never looked at my husband twice on paper. The good news is that my imperfect husband is much better than any fantasy partner I could've come up with, in spite of his faults. And the best news is, he loves me in spite of my faults. None of us are perfect, however that doesn't mean we aren't deserving of love.
