Please Come Back-Louis Tomlinson Fanfic

Marissa and Louis have been together for a while now. But Marissa is going back to the U.S to see her family. After leaving Lou, will someone come back into Louis's life and beg to be taken back? Is this someone...perhaps Eleanor Calder?
Will Louis go back with her or stay with Marissa? And if he does go back with El, is he making a huge mistake?

A/N: I don't hate Eleanor, I just thought this was a good idea...
