Can someone tell me about the Rachel and Puck relationship?

Well, they started going out at the start of season one, because Puck had a dream about Rachel coming into his bedroom through his window. Then a few days later, he was playing chitarra for Rachel in her room, and he asked her if she wanted to make out with him and she detto yes. Then they started going out..

Then Puck gets slushied, and Rachel helps wash slushie out of his hair, and he apologizes to Rachel for ever slushying her.

THEN, the Glee boys have to choose between Glee and football. Everyone knows Puck will choose football, but he suprises everyone and picks Glee instead. In fact, Finn is the only one who doesn't ...
Basically, it ends, because Rachel admits that she loves Finn, and Puck is in Amore with Quinn so they break up. It wasn't a nice ending, because Rachel detto "I hope we can still be friends".. and Puck walks off saying "We were never friends".

So there te have the story of Puckleberry. In the Run Joey Run episode, I really wanted them to get back together, but honestly, I don't think they will. Hope I helped :)
