because really... you do need to be ok with it... in the event that it does happen...
also... not to manipulate... but your W has to understand and believe that you ARE ok with it... because otherwise, she may likely believe that you are continuing to pine over her, will always be there, and will feel pressured by you...
The way to help her best in that... is to allow her to feel and believe that if she chooses to stay with you... it is HER CHOICE... not pressure nor manipulation... not from you... and not from anyone...
