Sorting Laundry

The entire poem "Sorting Laundry" seems to be a metaphor. The opening line "Folding clothes, I think of folding you into my life" sets the tone for the entire poem. The speaker compares her household chores to her life with her love. The speaker states that "towels patterned orange and green...reserved, we said, for the beach" and "pillowcases, despite so many washings, seams still holding our dreams". The comparison of her goals and dreams with this person to household objects reflects how her job as a housekeeper has influenced her life.
There is also an overstatement in the poem. The last stanza states, "a mountain of unsorted wash could not fill the empty side of the bed". The overstatement is in the "mountain of unsorted wash". Obviously there is not a mountain of clothes, but it shows the speaker's huge desire and need for this man in her life.
I thought that maybe this guy cheated on the speaker judging by the lines, "the strangely tailored shirt left by a former lover". I thought that maybe the speaker was saying that she was willing to look past that because of all the history the two have together and because she can't have a void in her life.
