Well, it's about communication, expressing wants and needs, and not suppressing it. It's understanding the triggering behaviors and thoughts. For my current sitch it's mostly too late, but I can understand WAW needs reassurance and consistency and follow through. I can work on that now, even though some of the detachment triggers her (like the not telling her what I'm doing and where I'm going). This is someone who has real anxiety about the separation and how I'll manage the kids.
The other is recognizing when someone I care about is upset. With WAW, she'd be in a growly mood, but I'd never ask. Again, tricky in DB because of detaching, but that is something I need to work on.
Lastly, it's about recognising insecure attachment in others, so when I date again, I can be sure of finding someone secure, as hard as that will be.
There is a lot more about accepting the differences of others, and the intimate actions that demonstrate love, but that isn't anything I can practise with now.
I guess if WAW genuinely wanted to save R, she would have shared that book earlier. Telling that she didn't.
