A quick hello is fine IMO. Your H is good at telling you what he needs/wants (my ring, a divorce, is my name going on the gift and blah blah blah) and somehow not seeing anything different from you.
Can you clarify what you mean here? What do you mean not seeing anything different from me? I haven't been calling/texting/emailing; I did my own thing at the wedding; etc. How else different can I act?
