Girlfriend is not a place, you can adjust your mind to accept or not, you can choose to break up.

If you don't have a narrow virgin plot and your girlfriend is not a virgin, it should have no effect on your relationship. All you have to do is love her, try to maintain this relationship and fulfill your promise to your girlfriend.

If it is really unacceptable, you can break up with your girlfriend. The established facts cannot be changed. Don't hurt each other and make both sides suffer.
