"Soap" Analyzation

I have done lyric analyzation for the past two weeks and I really like it rather than my other, in my opinion, more raw writing. So this week I am analyzing Soap by Melanie Martinez.
      The opening lyric is "Guess I better wash my mouth out with soap." This is clearly figurative meaning that she said something she shouldn't have said so she wants to "wash her mouth out with soap."
      Next it says,"I think I just remembered something. I think I left the faucet running. Now my words are filling up the tub." I think this means that she is running her mouth and saying too much and the last sentence means that she can't undo what she said.
      Then,"Darling you're just soaking in it, but I know you'll get out the minute." This means that the person she told is thinking about what she said and processing it (reference the saying "soak it in"), but he will soon realize what he wants to answer with.
      "You notice all your fingers pruning up." After research, this lyric means that if this person says yes, she predicts he will get tired if her after a long time. Since "prune fingers" are a sign to get out of the bath, he will feel a sign to get out of the relationship.
      "I'm tired if being careful, tip toe, trying to keep the water warm." This means that she was tired of keeping a secret, I don't assume this means that she is happy about telling it.
      The next line is,"Uh oh, there goes, I said too much it overflowed. Why so I always spill?" She knows she let it out and she regrets saying it because I assume his reaction was not ideal.
      The chorus is,"I feel it coming out my throat. Guess I better wash my mouth out with soap. God I wish I never spoke. Now I gotta wash my mouth out with soap." This means that she feels she will say more and she doesn't want to. Before she says too much, she decides to "wash her mouth out with soap" meaning that she will make sure she doesn't let anymore out.
      "I think I got myself in trouble, so I'll fill the bath with bubbles." When many people feel stressed, they take bubble baths. So Melanie decides to do so.
      "Then I'll put the towels all away." I think this means she is putting the towels away as metaphor for putting their old memories away/behind
      "Should've never said the word love. Threw a toaster in the bathtub. I'm sick of all the games I have to play." She said "I love you." He most likely rejected, and now to kill herself, she would put a toaster in her bath.
      In conclusion, this song means that Melanie told him she loves him. He broke her heart so she wants to wash her mouth out with soap and undo it like she never said anything at all.
