It sounds like you didnt react in a particularly ideal way to him confiding something in you, and you clearly betrayed his trust by telling others.

It sounds like he has taken steps to improve himself when he was struggling with something. I would suggest you do the same.

If I were him, I imagine I'd feel pretty betrayed by your reactions and would struggle to trust you again, but maybe if he loves you he will be prepared to forgive you. Either way, discussing how you handled it with a therapist might be beneficial to you/ both of you.
