I heard the same reference about someone being told to love their wife again.
My husband was at a point that he didn't love me anymore. He does again. Not being intimate was the reason for him. I did many things to kill the intimacy or desire for it. I think every marriage that lasts forever will face all those things and each of us has to grow past it.
I would start with trying to win him again. For starters..he loved you once, he'll love you again! Do the things that won him the fist time. Look good, no complaining, talk about things he is interested in...whatever means the most to him.
Boredom comes at some point to everyone. Intimate Issues by Linda Dillow gives some creative ways to entice your husband...it is a Christian book, though.
Step by step. Answers won't all come at once. But little by little. If you are willing to change and do so because you should and not to manipulate him...then you won't get mad when he doesn't respond to you immediately.
Him saying that he doesn't love you..or is bored. That can all change.
