I wasn't going to respond to this post but, i just couldn't help myself :).
I'm not a expert on love spells, because i don't happen to believe in trying to manipulate someones free will. But, you mentioned that you've tried "several" spells to get him back. Spells, when done with positive intent and properly will take as much time as they need to take. You mentioned that he's talking to you, that's a positive sign. Try relaxing, meditating and its quite possible that the answer as to what to do next will come to you.
If it were me, i wouldn't try another spell...
