Hi everyone!
Right the fanfiction I'm looking for is a G!P fanfiction.
From what I remember Rachel is the one with the G!P and she is the lead singer in a band with Puck and Sam. She ends up having a one night stand with Quinn. Quinn gets pregnant but doesn't tell Rachel until Rachel eventually sees Quinn one day with the kid. Quinn and Rachel end up getting together and raising a family. Something then happens where they split up for a brief time and that's all I can really remember.
Please help! PM or Comment :)
