Hey there. Yes, transitioning from playing as a couple to developing independent relationships with another partner is very common, whether the people in question are straight, bi, or gay. Keep in kind that your bf and your friend may develop a romantic relationship, and that this may NOT happen between your friend and you -- would you be ok with that? You can never predict or dictate how these things will go, so don't go into it unless you're open to staying flexible and seeing where it goes.
This website is a great place to get started, and may give you some useful thoughts for talking with your bf. I would particularly recommend this particular page -- http://www.morethantwo.com/coupledating.html
The major players. Me, 30ish bi female. Gia, girlfriend of 4+ years. Clay, boyfriend/dom. Davis, ex/friend/"it's complicated." Eddie, roommate & fwb.
