The man my mother left my Dad for... has gone MGTOW

My Mother kicked out my beta father twenty years ago, and moved in her Chad partner (to the family home my father paid for).

As a family we've have to tolerate him and his behaviour (he walked out of his previous family) and watch how my Mother was in complete denial.

Well, after a recent heart attack and cancer scare, Chad has informed my mother that he'll be leaving her; he wants to live on his own and vowing to stay single.

My mother has been sobbing since it happened, calling us all, saying: "why is he doing this?".

Me and brother are in fucking stitches by how deranged and deluded she is.
