Thanks for replying.
I am kind of new to this, but isn't a triad where all 3 people have feelings/love for each other? I don't think that is going to happen here. best I can hope for is my wife and my secondary partner are friendly toward each other.
As far as turning fantasy into reality, we have talked about that quite a bit, and have decided all we can do is communicate openly in the event I can find someone interested in getting involved as a secondary, and react accordingly.
