I support him.
I tell my husband about the posts on here where women intentionally get pregnant without telling their spouse. He realizes that some women are crazy so he told his friend to be careful when his friend told him his wife was busting his balls recently about having a kid.
He told her in no circumstance did he want kids before they got married so he ran out and got the vasectomy. I can see his wife tricking him. She's the type who will do what it takes to get what she wants. I think she's always wanted kids so she waited until she landed her dream husband at whatever cost it took to land him and now she will do whatever it takes to get pregnant.
Our state technically requires spousal consent and he told the Dr. he was married but also said that it was his body and like women he should have the autonomy to make his own medicinal consent. I support him doing this. He doesn't want kids, our kids are cool on occasion to him but not what he wants in his life.
I don't feel sorry for his wife. It's not fair to say, "Oh I don't want kids" and six months later change your mind.
