It is mutual, you are just think biologically though. Humans work on multiple levels, you ever talk to a parent about their newborn kid? Do you see how they talk about them? It's more than just biological.
Regardless, this issue is a little more personal for me. My ex (and I) had an abortion when we were younger.
Worst experience of my life. It was about 10-12 weeks in. And even at that point they had her up and it was like birthing a child. The fetus came out, it had hands fingers, arms, legs, had it all. Had a little penis and all. That was my little man, but didn't work out. When you see that and it's just lying on the table and it's dead and it looks like a baby....bruh....you have a totally different outlook on things. And that was me, women take that shyt a lot harder.
I'm just saying, there has to be some kind of cutoff, cuz at some point they are actually babies man..
