I think the time away from W will do both of you good.
Well, not communicating with W hasn't been too successful so far... W IM'd me about some stuff she left for me at D's daycare (movies + a bill for here that got misdirected). I was polite and happy, but short with her. I ended up leaving work this morning because I felt like I was going to puke, but ended up going by a couple of houses for rent rather than go straight home. I was walking around and decided that since I was close to W, I might as well ask her out to lunch. I called, told her where I was, asked if she wanted lunch, she said yes, I went to get her.
I picked W up outside her office. I'd not go as far as saying she was miserable, but she is very depressed right now. We did talk a lot on the ride and while we were at lunch, but W just seemed like she had no idea what to do with herself. She hardly ate anything at all over lunch - Said she was feeling unwell.
She seemed genuinely interested in my house hunting endeavors... She even suggested that I stay with her for a while until I get everything moved and get a new place set up. I've no idea if that is a good thing or not, but since I've got little more than a week before I have to be out of here, I don't think I have much of a choice.
