@Tuhin Emtiaz,
She said she wants time to handle this situation. This sounds pretty clear to me. I think it would be fair for you to ask how much time she will need (but she may not answer).
If it were me, I would decide the amount of time I am willing to wait for her (this would depend on the relationship and how deeply I felt for her). After this time I would shed a tear and then move on.
She has a decision to make. And, so do you.
