Since the chat group has been dissolved, there was no word from B till today. He texted, "I just back from open sea diving today. No earthly signal for last 7 days... Sigh... [Smiley face]" and so resumes our conversation again.
I do not understand why I get so affected whether I hear back from B or not. The only reason I can think of is that I am somewhat emotionally invested in the friendship we have. To what extent I am invested, I am not sure.
