Coping with Bi-Polar WAW

[CountingCrows]

I know I'm confused and still emotionally weak, but I'm questioning my motives. I'm having second thoughts about my true intentions for cutting W off of my WiFi. I'm thinking to myself "Am I just being spiteful and petty?". There's no cost or harm in letting her use it when she comes over. At the same time, allowing her to use it now would be backing down on a boundary I set, and would make me appear weak.

I really don't want to create more tension between us than necessary. We've got to get along right now for s7's sake. Am I just better off letting things stand where they are right now, and just try to have as little contact/talk with her as possible? I want so bad to tell her that I would like to try to at least remain friendly, but I know that's not what I should do.

I REALLY need to pick up No More Mr. Nice Guy...as I'm a classic case of one. Add it to my list of books I still haven't had a chance to read yet.
