Yeah she’s delusional. She never treated him like he was her equal, she constantly patronized him and treated him like a child. Yet, she expected him to contribute to half of their monthly bills and rent which amount to US$1300. That is an insane amount to expect from someone who is receiving a Dominican Republic salary.
On the other hand, he was cheating the entire time and just being obnoxious when he didn’t get his way.
The family seemed more toxic to me than him. Wasn’t the brother an alcoholic and the mother defending him?
