honestly? I think you should refrain from corresponding with her, even if she text messages you. YOU may know that it was broken, but SHE is probably grieving terribly. Who knows how direct your... boyfriend? was with her.

I think you did the right thing in saying that you're sorry, but don't offer to be friends and you definitely shouldn't lie. I'd just lay low... the more you get involved, the more it will hurt everyone.

Good luck...
