What to do?

My BF and I now have to choose between our other two girls this weekend. I am still sad about not choosing the girl we broke up with, but I would be just as sad with breaking Up with any of them. These feelings are so weird for me. I always wanted a hot, Sub girl to be a permanent 3rd for my bf and me. It is so hard to find a sexy girl who will date a couple and be into all the kinky things we are into. My BF always can find girls to have sex with us, but to find a no-restrictions, submissive, single girl Is the hard part. I can't believe my bf found these 3 girls all In one months time. These girls will do anything! They will do role-playing, toy-play, bondage, submission, humiliation, discipline, anal, dp or whatever else we can dream up. Their only request was that they would be our permanent 3rd and we would only have sex with them. This is what we wanted! Why do we have strong feelings for all 3 of them? Since our last LTR w a girl ended over a year ago, we have enjoyed our search for her replacement. We enjoyed the hunt and testing out all the beautiful, amazing, sexy girls we have been with this last year, but we didn't have feelings for any of them. This is def gonna be hard for us. We hope we choose the right girl.
