gleak - you can't control your fiance's behaviour, and you can't control her client's behaviour. i think you need to start trusting that she will make the right decisions. this whole thread to me reads like one big trust issue that needs to be addressed.

i do not work as a carer, and i do not know the professional code of conduct. what everyone else has said here seems sound, though.

but i dont think that your issue is limited to this one client. it sounds like you would be upset with *any* male that your fiance might have a friendly relationship with. i am 24, and i have a lot of male friends who txt me late at night, who i go out to lunch with, who would "lean in close" and ask me if everything is ok. if i had a fiance who had a problem with that, then i would have a problem with him, because it would speak of him thinking that *i* was not being appropriate, that i somehow don't know how to regulate my own behaviour.

if your fiance says there is nothing wrong with her relationship to her client, then i think you need to trust her on that. if there truly is something wrong, then that would be up for management to take action on.
