I would have to agree: unless you are absolutely certain she doesn't want kids, don't get married. Otherwise, one way or another, you're going to end up paying for the kids that she wants!
yah I could envision like 1000 ways where a guy who doesnt want kids yet gets married is totally and irrevocably hosed.
Off the top of my head:
1.) sabotages her own birth control
2.) has affairs almost continually because she feels entitled due to no kids rule of yours, literally your house is a massive gang bang the second you are at work signing out
3.) gets pregnant from affairs claiming your vasectomy failed
4.) feels you are less masculine after said vasectomy, has lots of affairs
5.) rides out the coaster until she is about 35-39 and then once she is nearing the "female wall of sexual marketability" just pops the chute, divorce and gets pregnant immediately afterward
Im not saying women or your woman is evil, this isnt about evil or evil intention. This is literally human evolution. Seems like you would baiting fate like some toolbag who keeps a grizzly bear as a pet and then is shocked it mauled him.
There is also NO WAY in heaven or hell I would trust someone else who said they didnt want kids. Are you a mind reader? Even professional military interrogators cant guarantee they are correctly assessing "unverifiable truth". How could you possibly imagine you are?
Trust is one thing, naivete however is a different animal.
If you actually water boarded your future wife and used a combination of mind altering drugs and classic interrogation techniques to ensure she also didnt want kids, dont post that. Just pm me, thanks.
