The relationship has turned sour, they have started distancing themselves from each other - "when the walls go up" - and the he wasn't "as honest as he ought to be" when he said "it didn't worry me", but it's actually hurting him - "hit me like an arrow"
"does it really fucking matter?" is the response he gets when he starts becoming concerned about what's happening to them, and so he becomes even more despondent - "okay, fair play, here we go"
The more this happens (and it's happened many times before), he becomes more insecure (which being "in love for real" has brought out) and thinks there is someone else in her life. He want's to "cross the line" of trust and check what she's typing to others - once trust is lost, everything is lost.
And so, the final verse is remembering how good they used to be and how much he would give to go back there. He ends with saying he's sorry since he knows that he's become paranoid, which will most probably lead to the end of their relationship
This song is how love often turns into paranoia
