So what in any of the replies has caused you to jump to the conclusion that you're ____ed?

To assume that there is not a single woman out there that would go for a guy that wants no children is quite honestly, simplistic and generalistic at best. Realistic outlook would accept the fact that yes, there may be fewer women looking for relationships without children in the future but it's not impossible ot find women like that

You can continue to think with defeatism in your mind but I encourage you to ponder this more.
