I agree just back off from him. If he has said there is nothing you can do then let it be. In all honestly if he cared for you as much as eh said he did he would not ahve left high and dry and not wanted to fix this. he would be more patient and understanding with you about this. And frankly, excited that you care about him as much as he (says)he does. Because that's not the case I still think he wanted a challenge. Just because he was in tears doesn't mean he didn't think of you as a challenge.
