"Grief; yes. / Analysis; of course." The poem begins as if halfway through an argument with itself, and the semicolons act like reluctant nods: fine, I'll grant you that, now let's get on. What the speaker gets on to is an "Escher path", a neat image for going over a break-up again and again, like M.C. Escher's staircases that climb for ever and arrive nowhere. The path's advice is blunt and circular ("It is. It is. Just accept it."), and its warning is the most vivid writing in the poem. Bitterness never "turned back time", it only eats memories, turns them "foul" and "belch[es] them back in your face, distorted." Memory becomes food gone bad, and the ugly verb "belch" makes resentment feel physical as well as pointless.
Everything after that is a pledge, and the form matters. Vows are normally exchanged by two people at a ceremony. These are made by one person, to one person, after the relationship is over, which is why the title sets "ex-lovers" beside "vows". The four numbered sections give the poem the air of a ceremonial document, but the voice stays plain and conversational. There is no rhyme, and the rhythm follows speech. Long, careful sentences are interrupted by short, flat ones: "Guilt resurrects nothing." "You do not deserve to be hurt." "We were good." These land like stones set down on a path of softer talk.
The first three sections are mostly prohibitions, and the repeated "I will not" has a wry edge. "I will not weep in public. I will not spout vengeful poetry" is a poem promising not to be a certain kind of poem, and the dry humour suggests a speaker who knows their own temptations. The hedging is just as telling. "I will try hard to keep" and "I will try to reflect, rather than ruminate" admit that these promises might fail. "Ruminate" is a precise choice, since it literally means to chew over, and it quietly links back to the opening's image of memories being eaten and spat out.
Section III shows the language doing its best work. The speaker refuses to "put you into a box / and label it with a number, shelve you in the newest slot in the entrance to my house". The picture is of past lovers filed like items in a collection, and the phrase "newest slot" hints that the shelf is already crowded. Against this cold cataloguing the speaker offers something warmer: "I will add you to the flavours of my life." The food imagery has come back, but now it nourishes rather than sickens. This answers the spoiled memories of the opening, which is the poem's main argument in miniature. Memory can be digested well or badly, and the vows are a recipe for the first way.
Section IV drops the negatives altogether. "I will never regret the knowing of you, the loving of you" is the most settled passage, a short stanza of plain gratitude: "enriched", "more complete", "part of me now." If the poem ended here it would be admirable but a little too tidy.
The ending is where it becomes honest. "In return, / permit me those odd moments" turns the vows into a bargain, and the speaker's price is small and human: a memory of "skin on skin", a thought of "what might have been", and permission "to keep on loving you / for as long as the need is there." The word "need" is ambiguous. It may be the speaker's own need, or the need the other person feels. Either way, the speaker has not stopped loving, only learned to carry that love without poison. The earlier "however hard it may be" now reads differently, because the discipline is hard precisely because the feeling remains.
The poem never says who ended the relationship, and that omission is what makes it widely useful. The focus stays on the speaker's choices, not on blame. Its significance lies in this: it treats a break-up not as a wound to display or an injustice to avenge but as a test of character. It also quietly answers the Escher path's "Just accept it." Acceptance here is not passive resignation but a set of small, deliberate promises.
