I am sorry to hear about your situation and feeling helpless to change things.

You wrote ‘In the past week he told me that he feels lost. That he doesn’t know who he is since he was in relationship for years, then briefly single and then back in a relationship. That he doesn’t know how to be in a relationship and work on himself too.’

He said that he needs to work on himself. If he has issues that need to be resolved, that needs to be a priority if you are going to have a future together.

At this point you are doing everything you can. It is up to him to work with his counselor and begin communicating
with you again.

Hope things do get better for both of you.
