Um, wow. I'm having a hard time focusing on responding to your essay rather than to the wild-eyed mapgirl27 screed. But I'll restrict my comments to your rational yet deeply felt essay because I am, simultaneously, on both sides of the situation. I have a daughter that I love with all my heart, but the very thought of having another child makes me weak with exhaustion. I dated a man last year who made me feel very lucky indeed, but he was as set on having children as I was opposed. And that is not the first time I have lost a good man because he wanted to breed. But I have to respect my limits, because being a mom takes more out of me than can be easily replaced.
When you have a child, you become willing to do just about anything for that child--sometimes to your own detriment. As a creative introvert, I need steady, solid doses of solitude and space as much as I need oxygen. I couldn't get that solitude/space as a stay-at-home mom, but neither could I deny my daughter the constant love and attention I felt she deserved. 2.5 years at home with a baby/toddler left me utterly drained and defeated. I learned that I couldn't take care of both my daughter and my former husband, and he was unwilling/unable to take care of himself. So it took its toll on my marriage too. From my perspective, when your girlfriend refuses to have children, she's choosing to keep the happiness you have together now rather than jeopardize it by deliberately introducing a life-changing event.
As I near 40, I begin to wonder whether I shouldn't reconsider my position. The older my daughter gets, the more I am nourished by the massive bond of love between us, and the more pure joy she brings to my life. It's so much easier to give to her, now that it's no longer a struggle just to make it to her bedtime so I can breathe. Now that I'm experiencing the outrageously wonderful benefits of my years of effort, it's tempting to think "Well, maybe I should do this just one more time. Especially if the right man comes along..."
But is the right man the one who understands and respects my desire to avoid the sheer, unrelenting dependence of a baby/young child, and the devastating toll that dependence takes on my emotional/mental health? Or is the right man the one who convinces me that our union is too sacred and our life is too beautiful to shy away from bringing it to its fullest fruition? If you can't convince your girlfriend of the latter, is she still the right one for you? Parenting raises such gut-wrenching questions, even in the fact of its absence.
