Assalaamualaikum
My parents have been having marital problems for many years (poor communication, arguments, etc) No effort was made by them to sort it out. My father (70yrs) then recently got secretly remarried to a woman half his age. He told my mother after a few months of doing so. She is devastated. We all are devastated. He is in the the tabligh jamaat. He says what he did is sunnah.
when he realized how upset and unhappy we were he said he will end the second marriage. Is it fine for him to do that? (Even though I doubt he will do it.)
