You have good advice to ponder,
The up side that you did not confront Him with his need of the saviour then, may have been wise: that you were impressed to listen, has earned your turn to speak into his life so to speak. "Now is the accepted time of Salvation." You mentioned Him being in a bubble, people in recovery are in a bubble, you are part of that bubble. Let Him know it's the Holy Spirit and that it needs to be more than a bubble from good influences of relationships but that He needs the Holy Spirit on the inside, to be forgiven and for life to make sense. "All manner of sins shall be forgiven to man but rejecting the Holy Spirit shall not be forgiven."
