maybe it would help to take a look at what your desperate feelings are really about. do you know why you feel you need the acceptance of this guy? did you have something like this happen in your past that this experience is triggering? if you deal with what this is triggering then this won't cause you so much distress.

i do think it would be best to quietly delete this account. as someone else mentioned you can get banned from FB for creating a false account. also, i would be really upset if someone did this to me. when others reject us it is usually because of their own character flaws. you can't change that in him but by being deceptive you are giving him a good reason not to want contact with you. please take gentle care of yourself.
