" Let go or be dragged"
You didn't get dragged back into her life and down that rough and bumpy road because you made the wise choice. Proud of you for that HL. I know it comes with a few pangs of "what if" but try not to pay any attention to those... you know where that road leads too. I would suggest that you could spare yourself those pangs if you finish cutting the cords... Blocking certain individuals on phone,email and social media has been a very freeing experience for me. Does it mean I never "wonder"... of course not... but it does mean I never have to deal with the actual realities.
You did good!
