I have to disagree with this. I have been with my husband for ten years. There were definitely times that each of us questioned the relationship and whether or not we were "in love" with the other person. We were lucky that we were never BOTH out of love at the same time, or we wouldn't still be together.
But I think something else needs to be said about love. It isn't just a feeling. Love is also a commitment. When you decide to love someone, you are choosing to love them no matter what, flaws and all, even when they are not very loveable. I think part of the reason our divorce rate is so high is that people think they should always feel those wonderful, warm and fuzzy, excited in-love feelings, and it just doesn't work that way. There are giong to be down times, and you have to decide if you want to stick it out or bail. But, before you really answer whether or not you love Adam, you need to decide whether you can commit to loving him--treating him kindly and making him your priority, and working WITH him to solve problems, no matter what--if you can't commit to that totally without second thoughts then you are not ready to love him in the way he deserves to be loved. If he isn't able to make that same commitment to you, then he is not ready either. Though, I would say he has already demonstrated some of that to you by sticking with you through the stress of the wedding planning, your illness and anxiety (which I am sure made you not so fun to be around), the stress and embarassment of the cancelled wedding, and the confusion of now. Has he treated you kindly throughout all of this? Could you have treated him kindly if the roles were reversed? If the answer to that question is no, then you don't love him the way he should be loved.
