Welcome to our forum.
The most important ingredient in just about any poly relationship is honest, considerate communication. So keep the communication channels wide open between you and the woman you love. Communicate often and well, and keep learning how to communicate better. You might want to do a search on this site for "communication."
That said, many other things are important for a successful poly relationship too, so have a look around and just explore this site in general. See what threads call to you, and post any thoughts or questions that come to your mind.
Glad you could join us.
Love means never having to say, "Put down that meat cleaver!"
