I think it's amazing when people realize their mistakes and god knows I've made serious mistakes in my marriage, as has my husband.
But, seriously, how do you not have the kids conversation? How do people get MARRIED without talking about kids and religion and money and politics?
Literally all my friends know my stance on kids. (I DO NOT want them at all ever, but would always want to live with/near my sister, who does want them.) My husband knew this before we started dating; and I knew his preferences.
Please, please, if you aren't married, don't wait until you are to talk about kids, money, and other really important things. Look up lists of issues to talk about before you get married and talk about them. Communication is everything. I know more about some acquaintances than their spouses do. It's crazy to me.
(P.S. I really don't mean to offend. I know it's culture not to talk about private issues and people come into relationships with a lot of baggage. I've done very abnormal things too. I just think it should be normal/expected to have these conversations, rather than just assuming women will want kids.)
