Say the truth, that you still are in love with her...
Even if you can't be together.
There is a certain fallacy...that once the dep gets help they will return to their senses and want to get back together.
Sometimes this is true...more times people have gone their own way, grown in different directions.
It is a waiting game, how long one waits is up to an individual.
I waited five years...before moving on...we were still 'in' a relationship...but, he didn't want anything deeper...so be it.
Along comes someone, more to my type, more in common, who shares a great deal with me...so break up with love of my life, and find my soulmate.
