I reread some things. This man is almost 41. He manipulates your emotions. After a year together, he is refusing to communicate and preventing you from communicating. You keep suggesting that if you could talk to him, you could fix things. You are hanging onto the past. Even if he unblocked you and stopped being immature, things do go back to being the way they were. They become the way they are.

The we in we can fix this means 2 people. You can't create a healthy dynamic alone. This 41 year old doesn't want to participate in a healthy way. I apologize of this is difficult to hear, and I don't want to cause you distress. You are not in a healthy relationship with good communication. Join a club and participate in activities you enjoy. Work on being the best version of you.
