For what it's worth my advise would be to **** him off, tell him you want space to deal with your own feelings and selfish as it may be you are not interested in dealings with his right now.
Maybe in a few months you can catch up for a coffee and see where you are at but other than that just to leave you alone.
That's exactly what I did to my ex who couldn't make up her mind about what she wanted so just ended up playing me like a yo-yo
Take some time for all the emotional stuff to settle back down and give him time to figure out what he really really wants because right now he will just suck you back in because he doesn't want to lose you, but you just open yourself up to even more heartache later.
