I completely understand the going slow, even H and I are going reeeeealy slow in our process.
Go slowly in your dating because it's the right thing for you to do, not as a reaction or counter to what W is doing. Even long term M and R breakdown. Yes, we can say it might have been better to wait but to continue to hold that resentment toward W can't be good for the ongoing R with her. (she will always be in your life)
A given is that your D will be hurt again and even tho we hate to see it, when supported through it they develop resilience. They learn to cope with real life, not shy away from if for fear of being hurt.
You do worry, mostly about things you have no control over. But it sounds like you're making progress.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
