We feel it all even if we ignore we still feel the same thing

Somebody said every day was gon' be sunny skies, Only Marvin Gaye and lingerie, I guess somebody lied We started discussin' it to fightin' then don't touch me please Then it's let's stop the madness just come lay with me And truth be told I'm wavin' my flag before it goes bad yeah yeah 'Cause we made it this far on for better or worse I wanna feel it even if it hurts If I gotta cry to get to the other side, let's go 'cause we're gon' survive oh We stay on the front lines Yeah but we're still here after the bomb drops We go so hard we lose control The fire starts then we explode When the smoke clears we dry our tears Only in love and war Sometimes you're my general, you quarterback all these plays Sometimes you're my enemy and I'm throwin' grenades We'll just be chillin' and laughin', I'm layin' on your chest Don't know what happened 'cause things just went left But here we go back down that road That's just the way that it goes 'Cause we made it this far on for better or worse I wanna feel it even if it hurts If I gotta cry to get to the other side, as long as you're there I'll survive oh We stay on the front lines Yeah but we're still here after the bomb drops We go so hard we lose control The fire starts then we explode When the smoke clears we dry our tears Only in love and war As long as we make up after every fight when it's over You know I'm comin' home right there where I belong I'm takin' off this armor oh-oh-oh-whoa-ooh-oh-oh And we stay on the front lines Yeah but we're still here after the bomb drops We go so hard we lose control The fire starts then we explode baby When the smoke clears we dry our tears Only in love and war Only in love and war Only in love and war
