ANSWER:
You married her after being given the opportunity to see her. You must fear Allah; how would you feel if someone married your sister, aunt or daughter and 2 months later wanted to end it because they don’t like her appearance? You take all her chances of getting married to a real man and now you want to end it?
Marriage is based on compassion, trust, and fearing Allah when dealing with one another. If you cannot give her a good married life, set her free so she can marry a real man who can!
