YTA, this has a major implication on the viability of your marriage, you should tell your wife so she can decide if she is okay with the thought of never having children.
On a meta note for this sub, I seem to remember a post from a few months ago in which a woman talked about how she had gotten pregnant and planned to abort without telling her husband, despite the fact they both had talked about wanting kids and he was operating under the assumption they were actively trying to conceive.
Everyone insisted that she was well within her rights, "her body, her choice," the husband doesn't get a say and doesn't need to know. But when this dude does the same thing, he's an obvious asshole, think about his poor wife! Yet another example of the massive double standard that exists on this sub.
