SECRET CONFESSION #06

I am a boy 20. When I was 16 I was deeply in a love with one of my classmates. After a long a time, we got into a relation. After almost 2 years of relation she cheated and got another relation with one of my best friends.

Then I abused her badly but later felt very sorry about that and she also felt sorry for doing that kind of shit with me. She had called me and we together said sorry to each other.

Now she is texting me. But the twist is she is texting me not for a relation once again else she wants her bf to feel insecure. In short she is just using me.
What should I do now ?
