How to convince my girlfriend she does not need to go on pricey dates?

[Float On]

It was very selfless of his girlfriend to yield to his wants to be child-free.

I wonder why he did not tell her he was not interested in having kids. I also wonder why she would, around year 14, still think her big day was going to come (followed promptly by a baby carriage).

By then I think she was resigned to "this is all I get".
