A betrayal is the choice of the one who made it. Unhappiness never forced it, and it is not the hurt partner's fault.

الأنعام

قُلۡ أَغَيۡرَ ٱللَّهِ أَبۡغِي رَبࣰّ ا وَهُوَ رَبُّ كُلِّ شَيۡءࣲۚ وَلَا تَكۡسِبُ كُلُّ نَفۡسٍ إِلَّا عَلَيۡهَاۚ وَلَا تَزِرُ وَازِرَةࣱ وِزۡرَ أُخۡرَىٰۚ ثُمَّ إِلَىٰ رَبِّكُم مَّرۡجِعُكُمۡ فَيُنَبِّئُكُم بِمَا كُنتُمۡ فِيهِ تَخۡتَلِفُونَ

Say, ‘Should I seek a Lord other than God, when He is the Lord of all things?’ Each soul is responsible for its own actions; no soul will bear the burden of another. You will all return to your Lord in the end, and He will tell you the truth about your differences
