The couple are said to have taken time apart so that West can concentrate on recording his next album, reports US Weekly.
"They are still good friends," a source said.
"Kanye is consumed with recording his comeback record in Hawaii and had to shut it all off. When he's in work mode, he can't handle a relationship. He told Amber he needs to devote everything right now to his craft."
However, the insider added that the relationship can survive a short-term separation and will pick up again in the future.
"I wouldn't say it's over for good. It's always off-and-on when it's convenient for these two. He doesn't go out anymore and she loves it, so he lets her. I wouldn't be surprised if they are seen together again next week."
Rose recently revealed that West saved her life.
