Songs about being a guy's second choice?

I've basically been talking to this guy for 2 months and when I made a move towards an actual relationship with him on Sunday he completely changed and rejected me and wouldn't tell me why and then I found out yesterday that he did it because he's seeing his ex again and I was just his second choice. He flirted with me and told me I was the only one and I poured my heart out to him and told him how much he meant to me just for me to find out he was being dishonest the whole time and really only intended to date me if things didn't work out with his ex. Music really speaks to me so I know any song suggestions about being the second choice for a guy would really help me pull through this tough time. I'd prefer current songs but it doesn't matter. Thanks to anyone who helps! xo :)
