Should I remain married to a woman I have not consummated the marriage with after two consecutive accidents befell me, in addition to my discovery that I do not love her after seeing things I did not notice before the engagement?

There is no connection between the two painful incidents and the marriage. They may even be a good thing, serving as expiation for sins, a raising of ranks, or a test. If you imagine that what happened means the wife is not suitable, this is a forbidden form of pessimism, because the evil omen (tatayyur) that repels and prevents a person from their need is shirk (polytheism). If your feelings towards her change for a legitimate reason, such as a flaw in her religiosity or character, then advise her. If she responds, then praise be to Allah. If she does not respond, then she is not a righteous wife. However, if the aversion is due to illusion, evil omens, or trivial matters, do not follow your whims, and be wary for your faith. Consider the matter calmly, consult people of knowledge and righteousness, increase your supplications and Istikhara (prayer for guidance), and have a good opinion of Allah.
