I've read a few threads on relationships from people who were the (sometimes accidental) OW/M, and wondering if they should tell the DW/H.
A question that comes uptime and again is why are you telling him/her?
Does it really matter why? Surely the us should know/Not know for the good of their lives, not how it affects the 'teller' ?
(Helpfully that makes some kind of sense)
