Single mothers make bad choices except for widowers
Note: The single mothers who are widows are an exception in this as their spouse/partner passed away which is out their control. In normal relationships. (Use your common sense)
In my experience from dating a single mother and other experiences from friends and family, single mothers choose poorly on who the father of their child is.
It's always the same story. Oh I didn't know that my baby daddy was going to abandon me, cheat on me, be abusive, a narcissist, a liar ect...
They choose to ignore any red flags or signs and have a kid anyway. Then they complain about the choices they made.
Only once they've chosen the option of short term pleasure and had their fun, only then will they want to find a good man to help take of their child.
This is why good men don't want to date single mothers because they don't to pay for the consequences of their actions. Also it shows any good man that they are irresponsible in who they choose to have child with as it is a lifetime commitment.
Yes we all make mistakes in life, but we know right from wrong. Life is all about the choices you make. So choose wisely or you'll regret it.
Edit: Use your common sense. Extreme cases of course are an exception in terms of abusive/SA ect... However some comments already prove my point, because there's a lot of hurt people out there. Instead of taking accountability and responsibility on what went wrong and how to improve. The first port of call is to blame shift to the other person, which doesn't solve anything.
