Have I any hope...?

[bashy]

So it's been a strange week. For the first time since I started this process i've really discovered what detaching means. It doesn't just mean going dark... but detaching myself from my WAWs life/problems/concerns/worries etc.
I've been trying to do that but, and there is always a but with me, she has been in constant contact this week about trying to get a new place for her and D as well as organising a financial adviser for applying for an IVA.
While I really don't mind helping her she really only ever contacts me now when she needs a favour. Ofcourse, she'll say it's not for her but for our D, so I'm left to feel guilty.
However, I'm starting to feel something stir inside me. Is it anger, hurt, resentment? I'm not sure.
So today I was busy online looking at a few things to buy for myself when it's my WAW ringing. I decide to decline the call. She tries again. I decline. Fifteen minutes later another call. I decline it again. I text her and say I'll ring in 15 minutes.
30 minutes later she rings again after I don't get back to her. I decline the call. I wait an hour and ring her. The first thing she asks is "Where were you doing?' with a kind of nosey laugh. 'Just busy with stuff', I say. She goes on to talk about her new place she's trying to get.
My question is.... what the hell is going on and what do I do about it? Should I proceed with not answering calls like before? Making her wonder what I'm doing? Turn off my phone so I'm not tempted to answer?
She's toying with me and I can't deal with it!
