I understand where you are coming from but couldn't she speak up if she wanted to? Or did she expect you to beg? No, friend you didn't miss an opening. SHE did!
On the same wavelength, again. As I was typing it, I was thinking, "They're going to say, "she can speak for herself. She can stop it, if she wants.'"
My uncle gave me some advice a month or two ago that I didn't fully appreciate until later. His advice was once I was done with the D, don't ever look back.
So, don't torture yourself with her problems and lack of willingness to work on the M.
