I have been married for a few years. During the first two years I was happy with my marriage and I loved my wife, but after that I started to feel that I disliked my wife. That is not because of religion, because she is religiously committed and has a good character, praise be to Allaah. Rather it has to do with her beauty, because she is not beautiful enough to keep me chaste and make me lower my gaze. I am afraid of mistreating her because I do not feel happy with her and sometimes I frown at her for no reason. The problem is that I cannot marry another wife because I am not financially able. I thought of taking a loan in order to marry but then I would be living in poverty because of the loan. I have thought a lot about divorcing her and letting her go in kindness and replacing her with another, but I have children from her and she loves me a lot. I have thought about this a great deal and it is disturbing my sleep, because I do not know what to do. What should I do, may Allaah reward you.
