How about.. tell him you love him, you are so pleased he is back in your life, yes you would love to continue to build an R with him, but that if he decides he cant do that full-time/in your house right now and wants to move away then you will support him and always be his friend, no matter what.
He's been a mess for the past 3 (?) years hasnt he, so it shouldnt be a surprise to you. He flipped, got stressed, depressed, lost his job, shacked up with a horrendous woman etc etc. He's still finding his way out of the tunnel Mish, I vote for loving compassion toward him.. as always. But then thats because I am a sappy push-over Piscean But hey, it worked for me, I forgave H the day we got back together.
