The single mom in question wants nothing and is content w/having complete control over the raising of her child w/out the interference and problems that are sometimes caused w/sharing a child. The child does excellent in school, excels in sports and it’s impressive how well mom does.
I do not believe this is the exception. Maybe at one time. But it is becoming much more common than you think. Maybe hard to accept. Men like to think women need them for support and conceiving. Heck, look at lesbian couples having children. Men don’t want to support or have kids. They are getting their wish. Women are doing it w/out them. Win-win for everyone.
