1-A thread like this is unlikely to go anywhere because it requires that we have first hand information on the various reasons performers have for stopping to perform and we simply don't.
2-In recent years many performers left the porn industry and they didn't mention the reasons for leaving but it's quite possible that boyfriend issues was the catalyst.
3-Is it possible that the performers you think left after a break up with their boyfriend were already thinking about leaving and the break up had nothing to do with them leaving?
4-Is it possible that performers want to have a meaningful relationship with a man and them doing porn is not conducive to that kind of relationship and maybe a recent break up with a guy they were dating shows them that they can have one but not both and they chose the meaningful relationship.
