What movie is this?! I saw a trailer for a movie where a guy goes back home & sees his teenage love.?

The image on rotten tomatoes was of someone, a girl I think, stood at the end of a pier looking out onto a lake. The film was a romantic comedy but I don't remember any stars in it.The premise, as far as I can remember, was two guys going home and there's a girl they fought over. It was an indie type film. Please help!
