After Michah's kind words, which I stand by completely, and I could not have put it any better, I want to share something with you as I was reading your note:

The phrase 'work with her' stood out to me. I think you repeated it twice. I think it is very telling of the frame of mind you are in and how you see this relationship. You work with a colleague, with a unit, with a problem. The fact that you feel you need to work with her is a sign that you are not getting your needs met and that your idea of a relationship may be hurting you.

If you feel a woman deserves your love and loves you as you should be loved you would not feel you need to 'work with her'...

Her lies, dishonesty and instablity causes you pain and I think you know the answer already. You have done well stepping out of the life that had and achieved status and appreciation. I think its time you did the same in your love life. Some times when we stop trying so hard that is when happiness comes. I would ask myself - what is my need to hold on to someone who does not love themselves? Maybe you want to rescue her (work with...) or change something you could not change before - whatever it is - put yourself first and see that your needs are met. We only live once!

Take care of yourself and I hope you continue to grow and prosper! And stay safe xxx
