im not expert, its my experience speaks.
Marriage is not about fighting or EGOs of both, and if you are thinking to divorce her and marry someone else you will be happy, you may think, but god forbid she may be wrost than before. so try to seetle whatever difference you have amicably. if you decided to end then go for mutual instead long legal battle, and wasting your precious days of your life.
if she is talking term, explain her what life is, if she wise she will understand, or else leave her for her fate. you both need parents, but your life comes 1st. keep away parents from your private life and do the duty of a son/daughter, ask them not intefer in your personal life or do something which she dotn like, and her parents should do the same.
most of the time girls parents ruin whole marriage. and girls do as her parents says.
tell her what you dont likes, and what she want and what you want from her. forget past and start a new life
Forgive and forget both for some extent.
Marriage is Bed of Roses with thorns
Kabi haan, kabi naa…
wohi tho jindagi hai.
Try your level best to solve this problem, if she talk legal, answer with legal language.
Rest up to you, its your life.
BEST OF LUCK
