Guy songs about heartache?

So I have a thing for one of my friends that is a girl. We text all the time and know each other very well. I love her but I don't think she likes me like that at all. She tells me about the guys she finds out that like her all the time and it rips me apart. Because I try to be a good friend and talk to her about her guy problems. Can you tell me about a song that is about a guy that doesn't know what to say to a girl? Or about a guy constantly getting hurt by seeing the girl he loves with other people? I'm really hurt and I would appreciate songs to relate to. Not songs about cheating or death. I would also prefer them to be somewhat modern. Thank you so much!
