First of all, amazing song! The chorus is so catchy.
As for the meaning, it seems pretty obvious to me that the writer is coming to terms with a relationship, either ending or going through some turmoil.
The lines "Don't I show it" are an intermonologue the writer is having about feeling like he is showing or expressing his distaste with the relationship whilst the character he is talking about seems to believe he is not expressing or communicating his thoughts and feelings.
