Need advice for a WW who left Part 4

[dwh15]

Just saw WW tonight for the first time in over 2 weeks. She stopped by to pick up S8 and take him to dinner. I did my best to be upbeat but currently fighting a cold so hard to come across as super confident and attractive as you're sniffling and coughing. But I smiled, made eye contact, and some small talk. She seemed in good spirits, which is a change from the past few times I've seen her, where she always seemed stressed and in a rush to leave. She took her time tonight and was relaxed.

So we discussed the plans for tonight with S8, then she asked if I would be willing to help build a computer so the kids would have one to play with at her place. I told her I had no money right now to help pay for something like that, and she said she would pay, but wanted help to actually put it together. I'm an computer guy, btw, in case anyone was wondering, and have a lot of experience with that kind of stuff. I almost told her I was too busy, but then S8 overheard us and got excited about the idea so I agreed to help, if and when she came up with the money. She mentioned how it would only be for the kids, not her, and I replied, I know, that's the only reason I'm doing it.

After they left, I went back to cleaning house and didn't think too much about it. It does bother me a little when I see her in a good mood, which I suppose is a sign I'm not totally detached, but I'm a lot better off than I was until just the past few days. I have reached a point where I'm no longer sure I want to be friends with WW, assuming we go through with D. I don't know that I want a friend who is so selfish, and willingly does such emotional damage to those she supposedly loves. But I guess anything can happen 5, 10 years down the road. Anyway, still feeling pretty good overall and looking forward to the weekend.
