Absolutely! My wife Pat and I just celebrated our 35th wedding anniversary. I never let a day go by without saying "good night....I love you", and on the weekends (the only days we wake up at the same time), we always say "good morning". I still drape one arm around her when we sleep too.
Never take the people that are close to you for granted, and never regard what they do for you as "part of the job". My wife cooks dinner every day. I have never failed to thank her for dinner, and most of the time compliment her on how it came out - and if she says something like "the meat was too dry", It always "tasted fine to me".
We are together voluntarily. I thank God every day for bringing her into my life, and I make sure she knows how much she means to me. I can't imagine my life without her.
