Law 10 - Infection: Avoid the Unhappy and Unlucky

I was a very happy and very lucky person before I got into my first relationship at 22 (I'm now 25) with a guy who deceived me of who he really was which is negative, pitiful and draining. Fast forward to today and I feel like I don't even recognize myself, I feel like I can feel his energy on me and I don't know how to get rid of it. I've become infected from him with his negativity and unluckiness.

In the book it says to quarantine, but I'm looking for more advice as I feel that may not be enough. Any tips or advice?
