Ariana Grande and Pete Davidson's relationship hit a road block that they just couldn't get over in the wake of her ex Mac Miller's tragic overdose in September, but neither of them feels responsible for the split because of it.

Still, the SNL funny man is having a hard time accepting that his fairy tale is over.

"He’s sad. He’s really sad about this split, and he only wishes the best for Ariana, but their relationship was really complicated with the passing of Mac Miller. It put a tremendous amount of strain on their relationship," a source dished to Us Weekly.

"Pete loved Ariana and wanted it to work, but they’ve both had such tragic events happen in their lives. And they are young. He’s really broken up about it. … He acts like he’s doing OK, but his friends can tell he’s beating himself up about the breakup," the source added.

We loved them together, but this romance seemed doomed from the start.
