Man, you've been unbelievably helpful the past few days. I cannot thank you enough for the resources, reading, thoughts and just plain compassion.

The more I process things the more I think that her lies/dishonesty/depressive cycles were in a way very manipulative. I also feel there were instances where she would abuse me. I distinctly remember an instance where she went out to lunch with a coworker (I had to work through lunch) and on the way back they came back laughing purposefully loud and obnoxiously saying "Oh that was SO much fun such a shame some people couldn't come!" 

It hurt me because I missed lunch since I was working, but their reaction was to literally tease me about missing lunch with them. When I brought it up to her she told me she was just "teasing" and she felt like I was insecure about her sense of humor. In reality it was just a hurtful joke to make, and reinforced this idea that if I missed an opportunity to hang out with her that I would be "punished" by her flirtations, jokes, etc.

Anyways, you've given me so much to think about and consider. Thanks for the help
