Quote: You know I really feel like I need to tell him this, I haven't and so maybe this is the "reassurance" he's looking for that can let him relax. And also include the "I will try to still be here if in the end you did decide I am the one you want to be with"
Ask for what you want! Tell him you want to save your M. Or work on a R with him. Don't ask him a question just tell him what you want.
If saying it face to face is a 180 than do it face to face. If you feel upset about telling him, then do nothing!
