Can love just disappear?

I'm together with a girl since more than 5 years. Since 2 years we live in the same apartment. The past half year a spent a lot of my thoughts about getting a full picture of my feelings. Sometimes more sometime less at the moment more, I do not know if there is any love anymore. I still like her she is a very nice person. Because of business I'm not at home for the next few month. It makes me said, that I cannot feel that I miss her. Most of you might think I need to talk to her. But it will hurt her a lot. I like her too much to hurt her and be honest. Is that maybe the last piece of love that stays with me? Did that happen to someone else out here? Will it come back?
