I think i would forgive her, because I have been in a situation like that before. At first I wouldn't forgive, and then when it was too late, I really realized how much I missed her and needed her as a friend. It was DESPERATE. Luckily she was still willing for me to forgive her, and this time I needed forgiveness too. At first its a little awkward, but it goes away quick. Just do it. You might regret it if you don't, because no one is guaranteed tomorrow.
