Is an older man already has kids (all adults) and grandkids, will he likely be with older women?

Our supervisor is in his early 50's. His current girlfriend is 42 years old.

He doesn't want anymore kids. He's ok with a mature life companion. All his 3 kids (from his ex wife) are all adults; the youngest being 19 years old. He's a grandfather too.

Is that one of the reasons a man his age (if he's doesn't want kids anymore) will look for an older woman?
