There's also too many women who genuinely don't take having a child seriously. When I was younger, the thought genuinely terrified me. If I was ever unsure about protection, I was straight to the pharmacy the next morning for the MAP. Yes, contraception is a joint responsibility, but only a woman can get pregnant. You have to take the lead on your own contraception.
As soon as I was "ready and open" to having a child, I stopped using protection, and, newsflash- it only took one time. Myself and my partner overhauled our (already decent) lives in 9 months. We bought a house with room for kids, in a good area. We sold his car for a family car (mine's getting changed this year). We ensured our finances were water-tight for when I was on maternity pay. We researched babies extensively and were as prepared as possible. Obviously, nothing truly prepares you for a baby, but we did everything we could. And we both aren't huge earners. But we saved and were responsible.
Far too many couples are blase about "if she gets pregnant". Far too many people fall pregnant to someone in undesirable situations. And neither do enough to rectify it. They know their situation is bad, but just lie in it, rather than getting out and getting the fuck away from it.
I'm aware unexpected pregnancies do happen. But if you're having sex, you should always have a plan for if things do happen. Whether that's abortion, a life overhaul, etc.
Really, though? Your life shouldn't need overhauled when you fall pregnant. A baby really should be prepared lovingly for- not threw into the chaos with the hope it'll turn out ok in the end. This is a human life, not a toy.
