Cover art for Better Than You lyrics by Friday Night Boys, The

i think this song is about an ex-girlfriend. where she probably cheated on him and when they broke up, she still stayed with the guy she cheated on him. then he is telling her that he found another girl, better than her and that she is missing out because he probaby doesn't care about her the way the singer did. although now he found someone.
