When you first fall in love, when everything is exciting and fresh, it is easier to be in love. Sometimes after a "stormy" relationship, you have to "choose" to love that person. I feel the song says, he can either let the relationship "pass by" by letting it end, or he can try and work out all the problems and salvage what they have. It's about taking an active role in your life and doing what it takes to get what you want. Not applying yourself will let everything pass you by including a relationship that needs some work.
