The bitching about him admitting he is worried about not having anyone to care for him when older is interesting....because that's the sort of comment that women without children get on a regular basis on here. Why is it supposedly ok for women to worry about that and not men?
I'm very happily childfree by choice and, personally, don't worry about the above, but for people who saw children as being part of their lives but for some reason didn't/couldn't have them then it is sad.
Many people have relationships where one partner does not want children, so they have to choose between staying and accepting that or leaving.
Some people find that they don't meet someone who they feel committed to enough for children until the time js too late.
Some of those people are men. That does not mean that they are inherently bad people, just that they share some experiences with women.
I too am mystified sometimes by the double standards and mental gymnastics that go on on here to class all men as bastards.
