Live, I'm thinking the same thing that Georgia is...there might be more to why he stopped seeing the IC. There's no way to tell and if he really and truly wanted someone who could really delve into his mind, he could have asked the IC for a referral or called around.
Listen and validate. As for the recommendation, I would mention it the next time you have a conversation, in person, text or on the phone. Don't be too quick to give it to him because it looks like you are attempting to fix him. Yes, he is most definitely a big boy and can figure things out and I wouldn't be the least bit surprised that he doesn't make an appointment or if he does, he'll find something wrong w/him/her as well.
Remember, you didn't break him, therefore you can't fix him. Hence, keep your expectations near zero or actually on zero. Keep the focus on you.
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.
