Communication is always difficult. I don't know who told you to be the first to end the conversation. Instead, you mirror the actions and accept the conversation. If he is in monster, always end the conversation. After all, don't stand there and take abuse.
What make the conversation awkward? I think a simple, "Honey, I am about to do ____, is there anything else you have to say?" It is not rude to end a conversation on a positive note.
I think it is very important right now that I do the right thing.
You are past the clingy, pleading, and crying stage. You are not pursuing and blindly trying anything to save your marriage. Now that you are back to being you and living your life, the right thing to do is what your gut feeling tells you to do. Follow that intuition and reflect on that intuition. If your gut is telling you to do the "right" thing, then you need to ponder what is the "right" thing for your h.
Post what you think is the right thing and then let people consider your possible action and give advice on what you plan to do. Then take it for what it is-advice. Not commands nor "must do's".
