You've been best friends since the first year, with Fred and him being your trio. George was always popular and had several girls behind him. While you were also very popular, you dated Oliver Wood, were the unattainable of school and were part of the perfect couple. Until in the middle of Wood's last year (you and the twins were in the 5th year of Hogwarts) he broke up with you and it was horrible, it hurt a lot (he finished for no reason and now after 2 months he has been trying to reconnect but you do not leave) but the twins stayed by his side. Fred always his best friend and George... became his stayer. You were friends in front of everyone, but at parties, on communal nights or in dorms, you ended up staying. But the truth is that they didn't know what was happening and were very afraid of losing their friendship.
