Welcome to our forum.
It sounds like you are in the beginnings of your poly relationship, and beginnings usually have the really bumpy roads. If you can hang in there and work through things, you can get to a time where things start to smooth out.
Triads are rarely made up of an equilateral triangle; the connection in one of the dyads is often more intense than in another of the dyads. Don't try too hard to make everything equal; just focus on getting each person's unique needs met.
Polyamory.com can help, so look around at the different threads and see what calls to you. We also have search and tag search. If you have any questions, just ask.
Glad to have you aboard.
Love means never having to say, "Put down that meat cleaver!"
