I love my family, my quiet parents, my lovely daughter, my diligent wife, we understand each other even without expressing anything since we have been together for so long, I feel calm and relaxed when I am with them at home, but I have always been feeling  that there is something insufficient, sort of boring, seems short of some kind of love or some kind of passion, do I really need to find a new love to enrich the sort of my empty life?  is it acceptable to have a lover out of marriage? I am confused. who can help me out???
