What's this song and who sings it?

The song that sounds like to me is called “stay” by sugarland. Here are the lyrics:

I been sittin’ here staring at the clock on the wall and I been layin here praying praying she won’t call it’s just another call from home and you’ll get it and be gone and I’ll be crying and I’ll be beggin you baby beg you not to leave but I’ll be left here waiting with my heart on my sleeve oh for the next time we’ll be here seems like a million years and I think I’m dying

what do I have to do to make you see she can’t love you like me

why dont you stay im down on my knees im so tired of being lonely don’t I give you what you need when she calls you will go there is one thing you should know we dont have to live this way baby why dont you stay

you keep telling me baby there will come a time when you will leave her arms and forever be in mine but I don’t think that’s the truth and I don’t like being used and I’m tired of waiting it’s too much pain to have to bare to love a man you have to share

why dont you stay im down on my knees im so tired of being lonely don’t I give you what you need when she calls you will go there is one thing you should know we dont have to live this way baby why dont you stay

I can’t take it any longer but my will is getting stronger and I think I know just what I have to do I can’t waste another minute after all that I’ve put in it I’ve given you my best why does she get the best of you so the next time you find you want to leave her bed for mine

why dont you stay im up off my knees im so tired of being lonely you cant give me what I need when she begs you not to go there is one thing you should know I dont have to live this way baby why dont you stay
