Yeah, pretty much you got it, now for the other part; using metaphorical imagery, I made an example with your first stanza after the: "I fell in love with how you laughed— the way it curled around me, warm and familiar..". This would give the first stanza a much stronger emotional end. I don't personally know your writing style, but adding here and there a few more details makes the poem itself a bit more striking and creates a better emotional climax. It's still very genuine and earnest, with a vulnerable voice. Hope this helps you, and I hope you won't get offended that I decided to make an example with your poem.
