Most Helpful Girl
It's hard to say he'll come back. You said yourself he's stubborn so even if he wants to, there's a reason why he can't be with you/feels like he doesn't want to be with you. If even through all his missing you and checking up on you through mutual friends he's still with this rebound and trying to get over you, he's not likely to just change his mind like that. But who knows. It may not happen as soon as you want it to. But don't get your hopes up into thinking he'll come back to you. That's the worst thing you can do.
