Not sure of the wiseness of getting in touch with OP. At the moment, you are treating it as something that is so below your radar that he is the one feeling guilty. Start contacting them and he will feel that you are being intrusive.
Big smack for the phone (but I'll let you off because of the pink nightie) lol.
Step back, breath deeply and no R talk at the moment. Is it going to change anything, or is it going to make you appear 'needy'. Let him raise it.
