Song lyrics stuck in head

"I'd sing a song that it be just ours but I sang it all to another love now I wanna cry I wanna fall in love but all my tears have been used up"
This lyrics reaallyy describe the situation that I'm living, he was the love of my life, that love who comes once at life, I used to draw him and sing songs for him, but he just left me, and now I'm looking for him in the others, I'm looking for him in another love.
