I would take everything out of that email that assumes or speculates about his feelings or motivations or thought processes. And I'd also remove option 5 - it should only be an option if you'd agree to it, and I think you're worth more than that, and you shouldn't ever communicate to him that you're not. If he is going to come back, he's going to need to work on himself, and talk to you about what went wrong, not pick an option from a list you have helpfully laid out for him.
