You're not able to live together forever. The love has upgraded to another form, which is represented neither by the eyesight, nor by the words, nor by the touch of body. It's only buried in the deepest place in your heart, nobody besides you two can share this love. Further, you do not enjoy this love, it's also a little bitter, only in the dark, quiet night can you check this love, together with tears. Everything is in memory only.
As to this point, you find there're not only one kind of love between opposite genders. You admit you love your current lover, but still you cannot throw away the other kinds of love deep in your heart. That's the fact.
