It sounds to me as though you need validation, which is something we all feel from time to time. The trouble is, you are not going to get that from serial dating or chatting with people you are not interested in. The way to deal with it is to bolster your confidence to the point where you don't need that validation. You are whole already, so you have to tap into that vein of knowing. To sound a bit corny... you have to fall in love with you. Because if you don't find yourself fascinating and gorgeous, no one else will.
