You gently encouraged him to seek treatment and then backed off when you felt that he was at his limit. You were supportive and encouraging but not pushy. You “stood your ground” but realized when to back off. You seem to be doing all of the right things.
More recently, he confided in you about his depression. This suggests that he sees you as trustworthy and nonthreatening. It is further proof that your approach is correct.
You should continue doing what you are doing. You can’t force someone to go to treatment. People are ready when they are ready and no sooner (and some people unfortunately are never ready).
However, he seems to be indicating that he might be open to treatment. Continue to be patient, supportive and encouraging. Hopefully, he will realize the wisdom of your advice. Please take care.
