Dear men,
Her being a single mother does not mean she is desperate for a man. Most men are into the habit of approaching single mothers as if she is desperate for a lay, or to settle for any man in the name of wanting a man to hold on to. 
We know it is right for every woman with children to want a father figure for her children, it is a natural instinct too.
But that does not mean she is desperate. That does not mean she can settle for any douchebag out there.
Some are married men who keep pressuring single mothers into illicit sexual relationships. Some even try baiting them in the name of he will support her child with this or that. Men, treat these ladies with the dignity and honor they deserve. 
She deserves a man not just a dickhead. She deserves respect. She deserves love and understanding too. Remember some have an otherwise bitter past so why should you be so selfish as to approach her wanting to even mess her life further? Be humane and considerate to them. 
If you cannot handle a single mother, just avoid her. No need to awaken healing or healed wounds of her past love life.
