It's OK

The speaker is unable to move on after a breakup. He notices reminders of his former girlfriend and imagines her with someone else, while admitting that he feels lonely and misses her. His feelings shift between jealousy, regret, and pleading for another chance. The repeated claim that it is “OK” for her to say she loves him sounds like an attempt to keep hope alive, even though the relationship may be over.

The “ghost” of the girlfriend suggests that her presence lingers in his mind, not that she is literally there. Her perfume in the sheets makes the memory feel vivid and physical. The tattoo of his name contrasts with the man holding her hand: she may still carry a sign of their past, but she is now with someone else. “Got out of hand” means his behavior became uncontrolled or excessive, though the lyrics do not explain exactly what happened.

The speaker asks whether she can regret him when she cannot forget him, but this may reveal his wish more than a fact about her feelings. His repeated insistence that it is acceptable to say “I love you” could be sincere openness, or a way of pressuring her to confirm what he hopes is true. The song leaves unclear whether reconciliation is possible; it mainly shows how strongly he wants it.
