Worst type of rejection - ghosting

Just had (yet another) guy who seemed genuinely interested suddenly stop talking to me. Worst part is he hasn't blocked me he just isn't replying. I practically begged him to tell me what I said because it hurt so much after talking for about a week and then suddenly stopping but to no avail.It always makes me miserable when that happens, especially when they seem to fit all my criteria as well. How is a guy who suffers from depression as it is supposed to deal with ghosting?
