Your story sounds so similar to mine. Work, woman, working together, etc.
What helps me is that I make sure I keep in mind all the unnecessary lies. That alone should be able to change your mind about this person. If she would lie to you about something simple, what wouldn't she lie to you about?
The one thing that haunted me for a few weeks was thinking... .damn! it was all a lie? No love? no Nothing? No friendship? She really moved on? etc... .and stuff like that. But if I remember correctly, I never trusted her. My mind was never calm while she was in my life. I wanted to go back in time and change the first time I addressed the first words to her. I really did think the worse of her, but then again she never gave me a reason to think good of her... .except for her words. But her actions spoke way louder about who she really was.
I knew detaching wasn't going to be easy for me because she was around me almost everyday for about 5 months. I also knew that if I didn't my life was over. I was just waiting for her to make her move and I was willing to deal with the pain if it came. I missed her but I never went to see her. She invited me over but I never went even though a stupid side of me wanted to. I knew it was only a matter of time before I she because just someone that I use to know. I just wish it didn't take her 6 months to finally disappear because that's the only reason why I even missed her. She was around me 5 1/2 months too long.
I still think of her. Sometimes I think I miss her but I'm smart enough to realize that I'm missing the person who I thought she was not the person she is. She is not nice and sweet. She is selfish and self-centered and she uses people. If there's nothing in it for her, she won't mess with you. That's all you have to think about. It might hurt but we are all capable of overcoming any evil. One day at a time. It gets easier as time goes by. Think about how disrespectful and deceitful she was and realize how that gig wasn't for you to begin with. That's how I look at it.
I had so much to do and w/o knowing I had put everything on hold waiting for the next backstabbing move she was going to make on me. Who can live like that? Can you?
Think about everything that happened, not about who she is with. Who cares! Just thank goodness she would soon be out of your mind and you can get on, hopefully with a normal life. Try to focus on you. You can even try feeling sorry for the next person she's with now
