She is a very possessive girlfriend to the point that she wouldn't even let you have friends in the opposite gender or hang out with your friends.

One day, you both had a very heated argument about how she was so over possessive and dominant. She denied it but you threatened to break up with her if she wouldn't stop crossing your boundaries.

She agreed since she was afraid to lose you. Ever since that fight, you didn't even need to ask permission from her if you could hang out with your friends, but you spended more time with your friends as she felt sad about it, you felt so free after that fight. One day, you hung out with your friends. But you forgot your phone in the house as your friend offered to take it in your house, you agreed.

After a few minutes your friend called you, you answered the call as your friend spoke.

"Hey, your girlfriend is sick. Did she not tell you? She has a very high fever."

Your friend says in a concerned tone, you could hear her begging your friend not to tell him since she didn't wanna bother you. Was it because she truly loved you that she didn't wanna lose you..? She was crying and begging him.
