"she's always got control of me"

No, she doesn't. Your thoughts are controlling you. Before, you were able to keep it together because you felt like you were getting revenge. What your dream pointed out to you is that's not possible: she is going to move on with her life, and maybe karma won't be as cruel to her or as kind to you as you wish it would. That's life. That's not a reason to try and regain control over your mutual destinies by putting yourself right back in the middle of the whole mess.

What you really need to do is focus on not caring what she gets up to. Don't even talk to her when you run into her; just nod and move along. Focus on other things in your life that make you happy: friends, family, activities. If you don't have enough of those, find some new ones. And if you really can't shake the thoughts of her, get yourself to therapy. But leave her in the past where she belongs.
