Did your husband get into the marriage willingly or unwillingly? If he was pressured into the marriage and was not naturally inclined towards it, then this will have a major impact on whether he wants to show love and affection. Also, what was his upbringing? Was he raised in a household that does not show love or affection? Was he neglected emotionally as a child? Also, what are his family's ideas on marriage? Is it just a formality where everybody plays their role? Is your marriage based upon friendship? I.e. are both of you friends and allies? Do you have conversations with each other? Are you from different cultures and have different understandings about Islam? Have you spoken to him about how you notice that he does not demonstrate love or affection, and asked him why that is?
