We actually feel badly for The Biebs!

Justin Bieber seemed pretty down in the dumps as he left church last night, and we have a feeling his breakup with Selena Gomez is hitting him hard.

Neither of them have discussed the split, but behind closed doors, word is getting out about the reasons why they just couldn't make it work.

A source tells X17:
    "Justin was totally blindsided when Selena told him she needed a break. He thought everything was going well, other than the stuff with her mom. He figured they could deal with that situation as a couple. He's devastated, but instead of acting out and making things dramatic, Justin has vowed to give her the space she needs and just focus on his faith. He really believes they're meant to be together in the end, so he's practicing patience."

For her part, the brunette beauty is trying to take each day as it comes and not make any rushed decisions.

Another source tells us:
    "Selena misses Justin, but her main priority is her health - it's literally a life or death situation. Stress isn't good for her, and the tension between Justin and her mom was giving her the worst anxiety. She is taking this time off for a couple reasons. She wants her family to come around to the idea of them being together, but she also wants to see how he handles things. If he's spotted out with random girls and starts behaving like he used to, she's ready to close the door on him for good."

We hope this isn't the end of Jelena!
