I'd share this excerpt from a Maya Angelou poem: "Every woman should know when to try harder and when to walk away." This is one of those walking times.
I also say, if he really wants to be with you,nothing can keep him away and if he doesn't nothing you can do can make him stay.
Lastly, "if you love something let it go, if it comes back to you - it's yours, if it doesn't, it never was."
I really think you should let him go & limit contact with him. Make him really miss you. If he wants you, he'll do what needs to be done to do so, otherwise- let him keep it moving. It sounds like he wants to enjoy the single life for awhile. The good thing is he cared enough about you to be honest with you rather than go and do his thing while pretending like he's committed to you.
eta:read the thread in it's entirety - OP, just take it one day at a time. That's all you can do after a heartbreak and it will get better with time, one day you'll just wake up and realize you're not hurting anymore.
