First, congratulations on breaking up with the first guy! 
Second, I'm so sorry that the second guy also manipulated you. Seeking revenge just puts us on their level (and who wants that!)
Now that you know the intentions of the second guy, the best "revenge" is;
dumping/forgetting him (and the first guy),
taking care of yourself,
and get a new guy (and hopefully "the third time is the charm").
Good luck, and welcome to Teen Hut!
