He implied that there is kind of romantic relationship going on. If that is the case, she would have told him about breaking up with her boyfriend to initiate a new one with him. But From what he said, there is nothing confirms that the relationship was romantic. So, since there were some actions like flowers and hugs after returns, I said me be she viewed their relationship as friendship. But then, she would have told him about her breaking up with her boyfriend, as I assume this what friends who hug and wait each others do. I should have said "she would have " and not "should have", though.
