I'm not ezactly sure of the meaning here ... but the battlefield as a metaphor for sex appears in the Grinderman song When My Love Comes Down, and the line "I'm not your favourite lover" appears in the Bad Seeds song Moonland.
I suppose, taking the metaphor further, Decoration Day here is used for fallen lovers/love affairs, instead of fallen soldiers ... and his ex hasn't even recognised him. So, possibly one partner's bitterness and resentment, and, in the end, boredom and/or possibly suffering at not being the other's "favourite lover".
