Get back at a Taurus!?

I was a relationship with one for months, I was faithful, honest and loyal. She told me she loved me and will always be there for me. Unfortunately, she never was honest and hid her feelings from me for no reason making it a one-way street relationship. She disappear for a week and when I confronted her, she was seeing someone behind my back and ran off dumping me.. (then dumping the hook-up a week later). Of course I'm pissed, so months later, when I was moving on..she pops up apologizing and tried to sweep it under the rug, being like it was no big deal. "Let's be friends, I mean we're cool right? **** happens, I missed talking to you and care about you". The damage was done cause she waited too long to apologize so I told her off. She's talking behind my back now and blaming me for things that I didn't even do. Making me look back then acting like I don't exist. I want revenge now. I just don't think she should get away with her lying and cheating.�
