Your W sounds insecure, uncertain, needy. It is easy to detach from that. I'm sure there are things about her that are attractive to you and those are the parts it is difficult to detach from - but all in all you seem to be doing a good job.
Is she aware of her issues or blind like my H?
I think she's totally blind to her issues. And of course, my efforts over the years to illuminate them to her have been woefully underappreciated.
