Portia, I agree w/FY as to him looking for something. Whether it's just ego kibbles or plain curiosity to see where your heart is right now, I would respond to his questions. Keep your responses vague and don't tell him everything. Sometimes, it's best to keep them guessing just a tad.
Something is going on w/him right now and he's told you a bit about his life. I would venture to say that it's not all rosy over on his side of the fence these days.
I do agree...he's going t text you back if you should opt to respond to his questions. It's time to bait your fishing line to see if he'll nibble.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
