Did you really want people to just see your point of you, or did you want them to agree with you and say your wife should not have changed her mind about wanting more children?
I can see your point of view. You must be disappointed.
You are wrong to think that had the roles been reversed posters would have commented differently. There have been many threads from women who's partners have changed their minds about being a father and the response is the same - if having a child is important they need to find a partner who wants one too. Being a parent should never be a compromise. You are either in or you're out.
The thing I'm curious about, as are other posters, is your wife's reason for changing her mind. I find it hard to believe you haven't actually asked her for a reason. I'm guessing you have but don't like the reason she gave. Maybe her health has changed and she doesn't feel able to go through the rigours of having another child and then the years of hard work raising another child. Or maybe, as this change of mind has occurred long into her relationship with you, she doesn't believe at this stage you would be a good father to a baby. Your comment that children love their parents more than life itself seems skewed to me.
As does your view that a man's point of view about having a baby is equal to a woman's. Do you really think the brief moment of ejaculation is equal to what happens to a woman's body during pregnancy, childbirth, recovery and breastfeeding? There is nothing equal about having a baby.
You said you just wanted to vent and yet you posted on a site where you know people give advice and opinions. If you don't want that it would be better to keep your venting in a journal.
