I don't think you need to worry about being mysterious right now. I think you should try to limit contact. Right now, your contact is too likely to get used against you. He's looking for things to justify his decision, and as you just found out, he will find them. Less contact, right now, means less walking on eggshells, and less stress for you. Which might lead to better rest, and more sweetness when you do have contact. Though I wouldn't be trying to show sweetness so much as mature respect. Validate his feelings, avoid relationship talks. Show that you are listening, show that you are responsible. Be confident in yourself.
