I have been paying a heavy price for remaining true to myself since I paid the first heavy price for this when I was a junior high school student. It seems I'll have to pay what seems to be the heaviest price so far - the price called divorce for the life decision I've made (and haven't changed for decades) to choose to remain childfree. Though the woman who is still my wife legally as of this writing told me before our marriage that she wasn't interested in children (and this is why I proposed her marriage in the first place), she seems to have changed since then. I heard from her for the first time yesterday that she has decided to choose her future children over me if she can't have both. I for one choose to remain childfree over her.
I don't remember meeting anyone who understood me when I told them even after marriage that I'm not interested to have my own children. Many of them were intolerant of this free choice of mine and even tried to convince me to change my mind. I have many reasons for preferring to remain childfree, but I've become tired of explaining them to those who have never doubted that having children after marriage is the only conceivable and legitimate choice. I'd like them to explain to me convincing reasons why they want or have to have children. If they accuse me for being egocentric in my decision, they look no less egocentric to me in theirs. But I'm alright with their decision as long as they don't try to impose their views upon me as I'm the one who has to pay the price of having children for the rest of my life.
Probably the sincerest account of people like myself who prefer remaining childfree by choice is Childless [sic] by Choice by Laura S. Scott, but the people described there are couples unlike myself both members of which have chosen to remain childfree. A more hilarious account is No Kids by Corinne Maier. They are far more eloquent than my possible account of myself.
PS (2017-03-19): In the meanwhile we met my spiritual mentor who also arranged our wedding. Before we met him, we were very close to divorce, but after our meeting smiles were back on our faces. Thanks to his insightful advice to focus now on the treatment of my OCPD and postpone the decision about children we seem to be able to avoid the worst scenario of divorce.
