I tried dating older men after I got divorced at age 42, but man alive - I just couldn't get into it. It wasn't that I didn't LIKE some of them - it was just that I could see the writing on the wall. When I was in my fifties I'd be taking care of some old man and his health issues, and then when he died, I'd be in my sixties and just about elderly myself.
Then I tried dating guys in their thirties. Wow, that was a TRIP. For one thing, a lot changed in that ten year stretch between baby boomers and Generation X. For instance, I got married young and actually had a grandchild I by the time I was 43. The guys in their thirties who I dated usually hadn't even been MARRIED yet - and didn't even have KIDS. Wow - that's a huge difference right there, even though they swore it didn't make any difference to them.
But I couldn't see any future in those relationships, and wasn't interested in playing the cougar role. I mean, these guys needed to get married and have kids - I was afraid they would regret not having kids of their own if we ended up getting married, and I wanted to get married, I didn't want to just have casual relationships.
I ended up marrying a great guy who is five years older than me and who has one son who was 12 when we got married (he's now in college). This has worked out GREAT age wise and we are get along fantastically. We literally never argue and laugh and cut up all the time together. We feel like kids together! I am glad I married someone close to my age.
