Personally, I don't think they really broke up. Yes Musa had teary eyes, but she did not seem that sad, like I think we all expect her to be if she and Riven had really broken up. I didn't understand that part too. Maybe Riven left for a few days, weeks or months because there was something he needed to do alone and will come back later in season 7 and Musa was sad because she wouldn't get to see him for a while...
