You keep going, you keep working on yourself, you don't need to worry about all the legal or material stuff right now. Give it a year, or two, to worry about that stuff, by then you won't be spinning and if it comes to that, it I'll be more like a business transaction. For now keep working on yourself, give him space to find himself, he needs to want to come back, and you need to want him back not need him back.
