What is the best revenge I could give my bf?

So a girl's bf messaged my bf telling him, 'Hey, Whats ur matter? My girl told me that you proposed to her during the Onam Celebration at school, and she told u she had a bf, and still u pleaded and disturbed her...........' his tone was so rude and angry. And I believe him because it's my 3rd time receiving a complaint like this. And also he does drool over all the women and considers me ugly. I just loved him so hard, so bad that I got cheated on.

I really wanna take some revenge. Like I rejected all the men just for him! I have more fans and more proposal count than him; like, I am admired and wanted by a lot of men, and I don't even glance at them. I barely talk to boys who have interest in me, and I also don't find interest in any other men.

But I really wanna ruin him as he did. If I want, I can get a man when I think of a man. I thought of using that skill. But I really don't feel like it would work.
