lyrics for a love song involving teenagers?

Hi, looking for help in a country love song about two teenagers who fall in love and then the guy moves on without the girls. Its based on the girls perspective. Anyway, i have tried loads of different ways and lyrics but none of them are quite right. Any suggestions?

Ehh.. this is kinda tough i guess. here are a few, they follow SOME PART of what you're looking for.

Julie Roberts :: Men and Mascara
Gloriana :: Over Me Now?

also, i'm sure you looked em up, but songs by Taylor Swift.
