I think in the end it's going to come down to HIM, if it's {and I agree with you that it probably is }an "out of sight, out of mind" thing,sometimes even with our moves,the other person has to be on the same page.Like, I'm on a Classmates site, and I noticed there's a family there that I used to be very friendly with, in fact, in that case, THEY even contacted ME{means they want to keep in touch,right?}Well, I responded, they either didn't answer, or responded one time, then "moved on".I've had people swear high and low they'll keep in touch, then got their attention on current things,and their not too strong promise fell by the wayside.Some people just have short attention spans.God has the POWER to change that, but with Him there's other iffiness, He doesn't always interfere with "free will",or it might not fit in with a bigger spiritual picture.I think you can make your moves, friend him on Facebook, call him.Can "out of sight, out of mind" be reversed? I've heard of it, in other cases, no. Your goal would be to find a way to reverse "out of sight, out of mind".
