Yes. Having an older partner can be very stabilizing, very secure, and very settled. There will be a LOT less chance he'll ever cheat, hide money, spend money on stupid stuff, or suddenly turn to drugs or alcohol.
At 42 he's probably decided what career he wants to be in, he's probably faced the fact that some day he's going to need retirement to live where he wants and how he wants. He's probably made a will, took a good long look at his life and decided how he wants to live out his days for the rest of his 30-40 years and had a sudden rush of OMG I'M OLD when he realized how short that number is.
So yes, if you are a good stable person who knows who they are, what they want, knows how to compromise instead of drawing a line in the sand, are not a Diva, nor are a wishy washy person.
A man this age is likely to want someone who makes them feel like a man that is capable, a man that has worth and meaning, and who is special.
But that's just my opinion.
Several of my friends and relatives have been married to older men or older women and those relationships have not ended in divorce or had much fighting in them. They were stable and calm but still fun. Just not as much drama!
