Have you considered blocking your W on your phone for a little while? If it is keeping you down, then you should do something about it. I know it is a bit of an ego boost to have her reach out, but she may be holding you back by doing so.
I don't hear from my W at all and in the big picture it drives me crazy that she could not care less, but your case is the complete opposite, but I think may be worse in the short term preventing you from moving forward.
