I think that this issue can be solved through prayer and study. I'd spend time writing down every day the things that you love about your wife. I'd pray fervently that you will see her as God sees her, and as a Husband should see his wife. I'm recently married, and sometimes the physical attraction fluctuates. Sometimes it's very strong, sometimes it's not as strong. Do seek counseling, and do pray and do all you can to make your wife happy. She's a daughter of God, and she deserves to have a husband that loves her more than anything. Don't be too worried because the physical attraction fluctuates. If you pray and have faith, and do what you can to make your wife happy, it'll come.
