Porphyria's Lover is a dramatic monologue that tells us the speaker's thoughts.
There is no conflict resolution: the poem ends with Porphyria dead by her lover's hand. No one has come upon them by the end of the poem and he has not been punished. What happens after this scene ends is unresolved.
There is no dialogue, either. The speaker of the poem tells us that Porphyria "calls" the speaker, but he does not relate her exact words. There is no dialogue in the poem. Finally, there are no formal stage directions. The speaker does describe several actions happening during the poem -- as when the speaker tells us he strangles Porphyria with her hair -- but we do not have formal stage directions as one would get in a play.
This probably means that the choice is yours. Your the author of the script of your life because you get to write your own story and make your own choices. Your the captain of your ship for the same thing. You sail wherever you want to lead your life too/
