Most Helpful Guy
Most likely to keep you as a back up, or at least to satisfy his ego that he COULD still have you if he wanted to. It could be to ease his quilt since this way it appears he is taking the high road and being civil after the break up. He might still want to be friends, but that isn't likely. Normally if you could still be friends then you wouldn't have broken up in the first place.
You have to do what is right for you. If you need to break all contact with him in order to move on, then you need to do that. This isn't about what he wants, this is about what you need.
