Not to butt in your business, but if that’s your only reason to not have children, and you’re otherwise financially capable and willing to raise kids, have you two considered adoption? Instead of bringing someone extra into this shit as you put it, you’d just be helping one of the people who’re unfortunately already in it.
Sorry for the late reply, was night here. Yes, we actually thought about that. But while it is easy to just have a kid, adoption (at least here in Germany where you only have around 4000 adoptions per year) comes with quite the list of requirements. We are both working full time and just recently found a very nice apartment, but without a seperate room for a kid. Then again my wife is a kindergarten teacher, so she already has like 20 kids ;)
