So he doesn't feel the same about you as you do about him.
If he did it wouldn't matter if you were in New York!
The only thing to do is get on with life. You really don't have a choice. Better to know he 'wasn't that into you' sooner rather than later when you'd wasted maybe years of your life.
Don't contact him, ask him not to contact you. You need to make the break as absolute as possible if you are to speed up the recovery.
Make a list of all the things you don't like about him,
1) Stringing me along when he wasn't really interested.
2) Keeping ringing me up though he must know it's upsetting to me
3) Thoughtlessness
4) Lying to me about loving me
5) Still trying to string me along ( as an insurance policy?)
6) Untrustworthy
7) Not involving me/ keeping me in touch with his plans to go.
etc.
You've got the idea, and read them over when you feel yourself weakening.
Now another list - aren't I lucky because,
1) I've found out what he is really like before I married him.
2) Before I had children with him.
3) Before I was inextricably entwined in his life
4) What a duff parent he would have been to our children - unreliable and untrustworthy.
Keep adding things.
Good luck.
Oh and get out, don't allow yourself to have time to think about it too much.
You need time and distance to do its work , visit friends, join clubs, visit family, make plans for holidays etc.
