Searching a song I once heard

[Elizaaahh]

Hi! 

I hope someone can help me find a specific song by posting it in this community. I’m sure I heard it multiple times in Spotify ads (in the Netherlands). I only remember a small part of the lyrics and tune. 

The lyric: “how can I love you, how can I stay if I keep on walking, (sleep?)walking away”. 

The frustrating part is: I can’t find the song anywhere! I’m sure that it’s an real song, because my friends recognize it too. 

Hope somone one can help me! :))
