Welcome to our forum.
I suppose you could confess your love to F and W, and tell them if they were ever interested in an MMF triad, you would be willing. But if it seems like that would just make everyone all uncomfortable, that's another judgment call.
In any case, it never hurts to learn more about polyamory, and this is certainly a good place to do it. Let us know of any thoughts, questions, or concerns you may have.
I'm glad you could join us.
Love means never having to say, "Put down that meat cleaver!"
