I've been where you are right now Denver and I believe I understand the powerful draw of someone who is willing to make things very easy for you when all you've been doing is working very hard for months on end. I couldn't fault you for leaning on that for awhile.
In an ideal world though, I think Gritter is right. It's better to use the difficult times to learn to handle your needs yourself without using anyone else as a crutch, even if they are a willing accomplice. Seems to me it's what your W did. Do you respect her more or less for leaning on OM when she was mustering the courage to walk away from you?
On the other hand, if you need the distraction and you're honest with yourself, I'm sure things will unfold exactly as they should. I hope you will be well.
