Cover art for Liquor & Love Lost lyrics by Bring Me the Horizon

I'm pretty sure that his girlfriend or now ex, did something to him that shocked him quite a lot, probably cheated on him, and he has no choice but to leave her even though he still loves her a lot? Since he keeps seeing her everywhere he goes. So now she's like a burden to him, even though they're through he's still hurting.
