Who are approaching 40 and single with no kids?
I know a few in this situation and they always say they feel judged and inferior to women of that age who do.
Personally, I do not feel sorry for them if they do not have kids as they are not for everyone. But I do feel for women who don't have a supportive and loving relationship. Now, I am not saying women need a man to be happy but I know from myself how much nicer my life is with DP in it.
