He is mentally in. His family and religion are more important than you will ever be. You are wasting precious time. All indicators are screaming it's time to run. He will try to hang on to his secret mistress.
He will want to meet up with you to pull your emotional strings, declare his love and make future promises which he will not keep. Do not believe him for a second.
Don't sell yourself short. Tell him to call you when he has a date to introduce you personally to his parents (he won't) and that until then you will be dating.
After 3 years it's time for action, not words. Make your break and make it fast and permanent.
