Someone Else's Heartbeat

I know it's not a thing And that I'm dramatic But I just can't help it that I still get jealous Yes, I know that I'm the only one in your bed But am I actually the only one in your head? So to-touch me baby Gimme so-something baby Cuz I'm running out of things to say to you We all got a past I don't judge you for that But I don't know how to tell you that I don't wanna know If I'm the only one who's ever called you "baby" And I don't wanna know If I'm the only man who's ever seen you naked And has been in your bed Cuz I can't imagine The thought of you dancing to the rhythm Of someone else's heartbeat You say that you're over it So don't take it personal "Baby he's just a friend That was three years ago." But everytime you say his name I start crying And when you ask, I lie and say that I'm fine Thinkin': To-touch me baby Gimme so-something baby Cuz I'm feelin' so far away from you We all got a past I don't judge you for that But it really hurts my soul cuz I don't wanna know If I'm the only one who's ever called you "baby" And I don't wanna know If I'm the only man who's ever seen you naked And has been in your bed Cuz I can't imagine The thought of you dancing to the rhythm Of someone else's heartbeat (Someone else's heartbeat, oh yeah) I don't wanna know If I'm the only one who's ever called you "baby" And I don't wanna know If I'm the only man who's ever seen you naked And has been in your bed Cuz I can't imagine The thought of you dancing to the rhythm Of someone else's heartbeat (Someone else's heartbeat) (I don't wanna know) Someone else's heartbeat, oh Someone else's heartbeat Oh, someone else's heartbeat Now every morning you roll over to kiss my neck You tell me "Good morning" and make me coffee Just like he did And when we cuddle on the couch with that candle I think that it's his voice inside my ears Cuz it smells like the one he got for Christmas that one year He was two years ago He was in the right place at the wrong time But when my eyes are closed I still think that he's mine Even though you got the Warm eyes and sweet smile that drive me crazy You got the smooth hands and lips that wanna memorize me You got the slow and steady Maybe someday start a family You got everything that I need So why do I sometimes still dream Of someone else's heartbeat? How does anyone move on from someone else's heartbeat? Oh, yeah
