Asslamo Allaikum,
Today many Muslims are infatuated with the concept of Love & Romance due to the continous bombardment of the Media. The truth is that you are supposed to treat your wife kindly and with affection even if there is no Love and display the best of Akhlaaq.
A man upon the Sunnah will look after the wife due to Fear of Allah (SWT) and continue to do so...Consider the following saying of Sayyidina Umar (RA).
قد روي عن عمر بن الخطاب رضي الله عنه أنه جاءه رجل يريد تطليق امرأته ، فلما سأله عمر عن السبب : قال : إنه لا يحبها ! فردَّ عليه عمر رضي الله عنه : وهل لا تُبنى البيوت إلا على الحب ؟ فأين الرعاية وأين التذمم؟

It was narrated that a man consulted Sayyidina ‘Umar ibn Al-Khattab (RA)about divorcing his wife and ‘Umar said to him: “Do not do so.”
“I do not love her,” the man argued.
‘Umar may Allah be pleased with him said, “Are families built only on love? Where is, then, mutual care and the maintenance of rights and duties?”
