Would I ever get him back?

We broke up 2 weeks ago and on no contact terms. We had our ups and downs, but the downs weren't harmless, at least to me i guess. Like he was so nonchalant and laid back type of a guy and i just needed attention a lot. We've been together for almost 3 years and we really do love each other and were about to get engaged. One day we fought like usual, but he said let's break up because of our different religious beliefs. I tried to compromise so we can meet in the middle, he said no because he doesn't feel the same about me anymore. I just know he's lying to push me away, i had this feeling that was confirmed by a mutual friend. He's just afraid to do better and work on himself, he thought the only way to run from the urge to change is to run away from the relationship. I'm still in love, still in pain, i cry all the time literally. What should i do? I don't know even why I'm typing this but i feel like I'm gonna die.

Would I ever get him back?
