Multiple sources confirmed the sad breakup news to Us Weekly with one saying, "He's devastated that it's over but it was for the best. They were spending too much time apart and it's only going to get worse this year -- the band going on a super long tour, her getting busier with university."
The source added that "too much long distance" played a big role, noting,"It was draining for the both of them and led to a lot of arguments. Liam was the one who chose to end it."
Another source squealed, "There was no way to maintain the relationship. He had to do it as they would never see each other and he didn't think it was fair to her."
Well this all makes us very sad, especially given Liam's tweets on May 2: "Can't be without you," "Worse thing I ever did was let you go" and "No all I got left is the thought of you." Sob.
