Hi Mike ,
it's usually the other way around, the newbies ask the questions!
Welcome. You didn't give away too much but here is a question or two to get you thinking.
First off, what would YOU want from a poly lifestyle? can you see it as something that would make you happy?
How about if your wife just found a girlfriend and they had a separate relationship that you were not involved in? Would you be happy with that?
That would probably be easier to achieve.
