There's an honesty in this sad piece that makes it a piece to which many can relate. It takes a good person to not be bitter when love fails.
The only suggestion I can offer would be to "break" after lines 7 and 14 and end with "regardless" standing alone as a strong statement. Having two stanzas and a concluding line (word) that matches the title might add visual appeal and emphasis. Of course, this is YOUR poem, but I like to share little thoughts when I think they might be worth consideration.
Bittersweet and concise, focuses more on emotional expression rather than word play, which isn't a bad thing at all =]. I really liked the line "Purged by salty tears divine". Good job, hope to see more from you~
