You likely have much more experience than me on this topic, but most men end up with a woman younger than them at most stages of life (post menopausal considerations need to be considered. Just sayin...).
The funny part about this is that out of all the ladies I've dated, only two of them have been younger, although one lasted five years. I own two businesses, one of them since my 20's.
I don't want sound like I'm placing blame, because there's plenty on my end as well, and the two businesses have a lot to do with it. Things didn't work out, but it wasn't due to bad people or betrayals.
