If you are both above 20, and she cares more about what her parents want as opposed to what you and her want, then leave her. She does not love you. A girl in love should not want what her parents want over what you and her want. That’s not how romantic relationships work. She should not be doubting the relationship, there are only so few scenarios in which you have a relationship with her would bring her harm – then in these scenarios, her doubt would be justified. It is 2017. If you want a relationship, then you can have. Unless she is being coerced, there should be no doubts in her mind if she truly loves you.
