After two years of dating—and a lot of time apart for work reasons—singer Nick Jonas and former Miss Universe Olivia Culpo decided to part ways.

A source confirmed to E! News that the two split because they just couldn't handle the time they're forced to spend apart anymore.

"This has been a sensitive matter and both of them still love and care about each other and only want the best for one another," revealed an insider. "The long distance and ups and downs have been weighing on the two of them lately, and it has not been easy but they know this is the best decision for them at this time."

Rumors of the breakup first started after they were both in New York City last week, but staying in different hotels, according to Us Weekly. A source said that the two didn't even see each other while in town.

A pal of Jonas said they are done for now, but doesn't know if it's going to last. An insider close to Culpo said their relationship was rocky for some time now.

On Sunday, Culpo tweeted a Maya Angelou quote that may have hinted at the separation:

On Tuesday, she also tweeted:

No official comments about the breakup were made yet by Jonas or Culpo.
