Do you make your sim self?

I made my simself for a challenge and I think I already told the story of how he got himself abducted and gave birth to a daughter at the second-to-last day of that challenge. Afterwards I'd play the two of them occasionally, but it turned extremely awkward when he got closer to another sim I had created. I saved father and daughter to the library where they still remain today.

The erstwhile love interest founded a family of her own. Two families, in fact. She passed away in my main save, but I'm playing her with another husband in a side save at the moment where she's one of the candidates I'm grooming for Get Famous. I really like this sim, just not in a romantic way.
