this is really difficult to answer and i was puzzled as you with the same question one year ago.
in fact, i am agreen that do our best to be together, and we continued, but at last,we said "goodbye" to each other.
now, if you really like him, just give him a chance, and if he aslo likes you deeply in his heart, you will be happy lovers.that's the best result we want to see.
even that one day you give up, you will not repent ,because you valued your emotion and you have the good memory between yourselves.
