I think that these he Is in a relationship with someone. But he feels like neither of them feel the same way they used to. And even though they don't have "feelings" for eachother anymore he is scared of ending the relationship and breaking her heart becasue he has broke so many hearts before. And in the line "you try to find a rythym in your heartbeat"
I think that means that they are trying to make it better and they keep telling themselves they still are into eachother, but its just basically a lie.
