Parthenogenesis became very common and babies started poping out of every masturbation and periods! Soon people realized that sperm and ova can be self-fertilized so that makes them potential living beings.. this made masturbation and getting periods punishable crime. Females started using pill to supress periods and men started practicing abstinence from it.

I think a main indicator would be how they react to you when you're feeling down or depressed. It's perfrctly normal for relationships, or friendships, to have conflicts. Two different people obviously have two different views on the world and different values. If they saw you vulnerable, would they ask you what's wrong and help make it better in any way? Or would they kick you while you're down? Try to put yourself in the same situation as well, would you give them a shoulder to cry on? Just some random thoughts that I think helped me recently.
