Falling out of love can happen to all couples regardless of how strong their relationship was. In order to recover the magic, you need to learn how to be affectionate with your girlfriend. There are different ways of learning. You can ask an older man in a successful relationship for some advice. You could talk to your friends but do yourself a favor and only listen to the ones that are happily involved. The others are single for a reason. Or you could buy a great book, read it and put the theory into practice.
