I think generalizing that a man that parties at 30, 40 or any other age is [insert stereotype here] and that they can't expect a woman to stick around that's their age, kind of is thinking too much as if your view, your values etc are shared globally about such things. The way to think of it is this. There is truth in the statement that any man or woman that at any point of their life is a person who likes to party, is connected with someone not into it, it's not going to work out. period. has nothing to do with age whatsoever. there is no requirement that at age 40 one should have stopped partying any more than it is a rrequirement at 20 that someone should be partying. I've never been one into such things at any age. I've been to a few but never been a regular partyer. so I never have wanted a woman that was to go out partying every weekend at all. not appealing to me

At this point of your life you happen to have outgrown it, but just find some guy that isn't into it - whether he's outgrown it or never has (partied) and you'll be happy with that aspect of the relationship.

I just actually think assigning a level of maturity or set of values to a certain age will always mislead you.
