Similiar situation.
My suggestion?
If you think she's worth it, then you should be a good samaritan
and get her emotionally stable.
Thereafter, pick up and move on. It'll hurt more to see her going
her way, but still a good deed done.
Well...if you think you should take a break yourself. Then got to
respect yourself too...leave her and don't suggest a cut off
period.
Occasional calls is ok. But keeping minimal contact is best.
How long have this relationship been?
Cheers
