Sounds like to me the ruination of a perfectly symbiotic relationship. And - I don't mean to be mean or condescending.
However, if this sex worker feels the same way about you, maybe there is an opportunity for a meaningful relationship.
Although I don't have all the facts, maybe you are attached to a SO and it could be the same for the sex worker. That also complicates everything.
I am not sure any of us can deal with having a relationship with a woman that provides sexual services to other men for a living.
I think it may be wise for all of us to make sure we don't get too regular with any of these sex workers and remember they are just the same as your auto mechanic.
They provide an invaluable service to us all but DO NOT GIVE THEM YOUR HEART.
