Why does he (married, in process of separating - 38M) keep taking off his wedding ring around me (single 38F) but putting it back on when around her?

If my doctor sends in a new prescription for Adderall to a new pharmacy (ex: I filled prescriptions at Walmart before and I'm switching to CVS) will CVS see when it was last filled at Walmart? Will they refuse to fill if it's 4 days earlier than my last fill at a different pharmacy?
