Disappearing just means staying exactly as you are, and when he deems it a whim he will call you up again to take care of his needs, be it emotional or physical. I say you confront this situation in order to close the door for good. Tell him that because of how things have been and the lack of interest you are concluding that the relationship (or whatever it was) is over, therefore wish him good luck and a good life but that you will no longer wish to be in contact with him as YOU are moving on..
oh my yes.
