Red flags... I see them everywhere.

I haven't written in nearly a year.  I don't know how to function on my own.  I am afraid to find someone.  I have made far too many mistakes in the past.  I see red flags in every person.  I swore to myself one red flag and I would refuse that potential.  A single warning sign.  I wonder is it possible for a person to have no red flags.

Can one person be free of red flags? 

Is it fair to ask that, when I wear a couple myself?

Am I making excuses again for why I don't want to date?

What cancels out redflags? 

Is it okay to allow certain redflags?
