I suppose it depends on the circumstances as to why they became escorts and I refer to those that choose to become escorts as opposed to those that where forced or trafficked.
I have met a few younger girls, early 20's prob, who told me they were at school studying for business or medical qualifications and tbf after a few tours they where gone. So that could be a possible outcome for some that retire from escorting. Others could have Student Loans or other such debts to pay off, so they can come here where there is a very low chance they'll encounter someone they know.
Others probably find new leases of life, a job they like (not saying girls don't like escorting but you know what I mean, I hope), possible relationship etc.....
In all honestly I think the escorts just go back to do what they were doing before escorting with a little more money saved up.
Holding on to anger is like drinking poison and expecting the other person to die
