After I left this girl, I thought I would get over it quite easily. And for a while I was fine and even happy. But now I think about it a lot and I wonder if I should try and go back. At first it was only a few thoughts of regret at night (I didn't seem to feel it during the day) but its only gotten worse (Its starting to get into my daydreams). Especially whenever I hear this one song, Sleep On The Floor- the lumineers, I get a pain in my chest and a longing for her. Im pretty sure I know what i should do, but some reassurance always helps..
