He wants you guys to be buddies for life. No commitment but the friendship is there. This only tells you that you need to detach (with love).
That means go out and do things for yourself. Find yourself again. Enjoy your own company. Don't expect him to fulfill you.
I don't agree that he needs to think he can lose you. That will only bring him back because he's jealous and those reconciliations aren't firmly grounded.
