We have to wonder if he feels partially responsible for this?

Justin Bieber was comforted by pals at church last night as he learned of ex Selena Gomez's mental breakdown and hospitalization, and it was pretty suspicious that fiancee/wife Hailey Baldwin wasn't in tow. Perhaps he told her he needed some alone time to process his emotions?

People are blaming The Biebs and his lady love for pushing the "Come & Get It" songstress over the edge with their engagement and secret wedding, and it couldn't have been easy for her to watch him move on so publicly and permanently. Mind you, it was less than six months ago that JB and SG were trying to make their own years long on-off relationship work!

A source tells X17:
    "Justin feels horribly. He knows that she's been dealing with her lupus and kidney transplant complications, and all the depression and anxiety that comes with it, and now he regrets throwing his relationship with Hailey in her face. Even though they're not together anymore, Justin will always love Selena. He's in a tricky spot because Hailey has always been insecure and suspicious of Selena, so he doesn't know how to proceed. He wants to reach out to her and have some closure, but Hailey has forbid it."

Why do we feel like the "Sorry" crooner is on the verge of his own mental breakdown?
