Hi, I 'm sorry for your dilemma. The advice I give is what I would do, should I be in your scenario. To answer your questions:1) It would be in your best interest not to see him tomorrow.2) He is likely experiencing an internal dilemma himself between ending your guys' relationship and still continuing it. He may actually not follow-up with tomorrow, unless you seduce him to do so or insist.
3) It is doubtful he is being maliciously manipulative, but rather, as I mentioned, not sure himself what to do. On one hand, you both fulfill each other's short term needs, but in the long run, it is damaging.
Finally, what you can do is what I have done in these kinds of relationships. Take 2 weeks to yourself. Leave the town where both of you have spent time together, and avoid any contact with him whatsoever. No social media, cell phone, or anything. Then, in the meantime, I would actually recommend using the mobile application Tinder and making a dating advertisement on Craigslist. See how much you are desired by other men, and within safe settings, see them. You will be flattered by all the attention, and rebounding will do your sould wonders. Best of luck. You can do it!
