So, according to you people, I shouldn't really leave him, and still hang on?
Eventually the decision is yours, but if you have,
no better alternative and have some hope with strong feelings,
then yes.
Just be strong and don't lose yourself for this matter.
Please remember: Aur Bhi Gham Hain Zamaane Mein Muhabbat ke Siva!
(There are other things also in this world to worry about than love)
Good Luck!
