Mut'ah is abused! do we seek Mut'ah to seek Allah's pleasure or His nearness or just to fulfill our desires? whatever the case Heسُبْحَانَهُ وَ تَعَالَى knows about. let us not deceive ourselves.
Should (Allah forbid) OP find himself in a wheelchair someday, would he divorce his wife so he won't be a burden for her?
we have desires, yes! desires are the lower self, let go of yourself & be true to your lady, who knows, maybe youe ssalvation is with her
with her chubbiness, it is just a test! Allahسُبْحَانَهُ وَ تَعَالَى man is ungrateful! & in surah dahr Allah says, '
Has there also passed on man a period of the endless time when he was not yet a thing worthy of mention?1 Indeed, We created man from a mixed sperm drop,2 to try him,3 and therefore We made him capable of hearing and seeing.4 We showed him the way, whether to be grateful or disbelieving.5
sorry am running late but read surah dahr to understand your position
and am a nothing...
