The pop star, 25, and Saturday Night Live actor, 24, started dating in May — the same month it was confirmed she’d ended things with the rapper — and they were engaged by mid-June. On Sept. 7, Miller died at age 26 from an apparent overdose, and this past weekend, Davidson and Grande broke up. A source close to the “No Tears Left to Cry” singer told PEOPLE that “It’s true that Ariana has been struggling a bit with life in general,” after her ex’s death, adding: “It was devastating and shocking to her. It’s had a huge, negative impact on her life. It made her rethink many things in her life.” Ariana Grande and Pete Davidson End Engagement: ‘It Was Way Too Much Too Soon,’ Says Source John Shearer/Getty Ariana Grande, Pete Davidson ‘Still Plan to Spend Time Together’ After Ending Engagement: Sources One commitment she ended up reassessing was her imminent marriage, the insider continued. “She realized that planning a wedding right now felt very rushed. It’s not what she wants to do right now.

These followers and living their lives on social media … it’s a different world.” In the wake of Miller’s shocking death, a source told PEOPLE that Grande “completely broke down after she found out about Mac… She can’t believe he isn’t here anymore.
