Does Pete Davidson Blame Himself For Ariana Grande Breakup?

Pete Davidson may be incredibly upset over the end of his engagement to Ariana Grande — but is he blaming himself for it?
One insider says the SNL star knows well enough it was nothing he did.

The way the new source tells it to UsWeekly, the big turning point was the death of Ari’s ex, Mac Miller:

“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.”

The source says they both feel some responsibility for not being able to keep it going:

“Pete loved Ariana and wanted it to work, but they’ve both had such tragic events happen in their lives. And they are young.”

We suppose that kind of shared deep emotion is how they got engaged in like two days in the first place.
As much as we hope the first source is right, however, a second source says that’s just a front he’s putting up:

“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.”

Oof. That certainly feels more in line with canceling comedy gigs.
Do YOU think Pete blames himself??
