Just a question for mgtow

So my parents have been married for 25 yrs with no infedelity (as far a I know ofcourse) and this is the case with most of my aunts and uncles and their relationships. Ofcourse there have been exceptions.

My mother ran her own business with 2 of her friends for 10 yrs and retired 5 yrs ago. My dad worked as a teacher and retired 3 yrs ago.

So my question is when you guys say AWALT do you mean everyone or is this just a trend or your personal experiences. Im new here and would like to know what this concept means exactly
