I would not want to remain polyamorous, but I believe she would. I know the gentleman (and his wife) and like both of them, so don't believe there would be any issues with her continuing along that path.
The other things I mentioned in my initial post -- not telling her about things like the online betting and creating profile on dating sites -- are the trust issues I messed up with before. To that end I've become an open book as far as emails, banking, Facebook is concerned.
I didn't always used to tell her where I was going when I went out ... or if I did it might not be who I said I was going with. Maybe taking pics of my male friends when we're out (at least initially) would help with the trust thing?
