My wife and I share a mutual friend, I really enjoy her company?

When the phone rings, I hope its her. When someone knocks at the door I hope its her. If I get a text indication, I hope its her. If she has dinner with us, the food tastes that much better to me. I laugh more when she is over. I just really enjoy being around her. Everything is so much better when se is near!!!....What do you think, is this normal to you?
