i can't see where your going with this '' closure thing''.
I agree with jno here, i think your either hoping for one last chance, or for him to admit the relationship has been a failure on his behalf, you've admitted you really like him and your pretty sure he dosen'y feel the way about you, theirs the final chapter in your book, you don't even know what questions your going to ask him, so how do you close it out then?
I feel that you don't like rejection, and you can't understand why he's not interested in you, and its eating away at you, hes hardly going to pay you compliments if you require ''answers'' before you split up, theirs many men out their who see a good thing and take advantage of it, he knows if he says the right things to you, it will buy him more time etc, its best not to contact him even tho you like to close things out this way, if the boot was on the other foot, do you honestly think he would want to close things out before he moves on?.
i just think he'll hurt you {verbally wise} if you insist on answers, just close this book, and pick up another one, don't look back, look to the future
Best of luck
