Look at it this way.

1. You stay with her out of pity.

What will this accomplish? It will drag out a already dead relationship with false hope only to come to this very point once again.

2. You try to help her and yet want to remain broken up.

This will let the good intention be known on your part, but seeing your face and hearing your voice will only make her more sick to her stomach, and more than likely way worse off than without you.

3. You tell her you never meant to hurt her and walk away.

This will hurt more than she will ever have known, and if she can make it through the first month she will more than likely be ok.

When it comes to reality, number three is your only real option unfortunately. IMO atleast...
