OK, great. Now go a bit dark for a while, let this sink in. Don't intiate contact for a week or so, see if he does. When he does, stay vague. You can tell him bits and pieces, just not everything. Be forgetful about giving lots of details. But mainly try to keep the focus of the conversation on him and what he's up to lately and talking about his interests. Then see what happens. The goal here is to eventually see him take a little step towards you in some way. Something like he invites you to lunch or a cup of coffee.
