... You might want to talk to her, she may be suspecting that you got a vasectomy because you're cheating on her. If that isn't why, she's being ridiculous. Sorry man.

That is something huge you need to discuss with your SO before doing it. Was she trying for one last one only to find out you had a vasectomy behind her back? That feels very deceitful and untrustworthy.

yeah so having a vasectomy - totally reasonable, the fact that you didn't tell her - totally unreasonable and I'd be hurt as well, not because she's entitled to force you to have another child, but why on earth would you hide something like that?

Your body, your choice. As she is your wife, you should have mentioned it to her first. Is she very religious or something?
