As much as I'd like to contact you, if I've done so once already and I didn't get a response from you or your response lacked interest in talking to me, I'm not likely to initiate the next conversation. The only exception would be if I know for sure you are in trouble and need someone to be there for you or if you're super close to me. You take a step towards me and I'll take a step towards you. If you retract, I don't move. I'm still there if you need me.
