I hate the hysteria of this forum, I really do.
no one can offer an opion without some rabid, face clawing nutter militant screaming "mysoginist".
personally, if I were the Op I would cut his balls off and saute them, possibly roll them in aspic and feed them back to him - but then I'd have another apologist arriving and telling me I had violent tendancies.
There is a lot to be said for spleen venting (be that here or with a councillor) and there is a hell of a lot more to be said for decorum, dignity and class and keeping ones own council.
Shall I lay it on the line? The OP herself said her ExH didnt find her attracive and she was initiating intimacy. Well, sing it from the rooftops ..... "My husband finds me so unattractive he'd rather pay for it".... because that IS what the average Jo/e will have, fleetingly, run through their mind. If the Op follows through her FB threats, all his mates will think she is mad, scorned and think he was right to look elsewhere because she will come across as unhinged. All the mates GF/DW/partners will pity her ..... ah yes, back to pity.
I guarantee you he will not be the one ostracised.
