Have you read about 180s? If emotional closeness and better communication is your goal, there are some obvious 180s you could do that would probably improve things.
Your husband opened up to you about a scary physical symptom, and you seem to have made the conversation all about why he didn't tell you sooner. This would have been a good tome to validate his feelings and thank him for communicating with you.
If you get upset every time he shares with you, you are actually discouraging future communication. (I had to learn this too.)
And then you get angry with him because he shares something he thinks is funny. I don't like strip clubs either, but was this the moment to make that point? Your husband had a rough call with your son, he's worried about his health, he was drinking. Was this a typical response for you? If so, how could you 180 your response to things you don't think are funny.
My communication 180s were a big part of the work I did on me, so I saw firsthand how much I could improve our communication by changes I made.
You can do this!
