Somebody have mercy and please tell me what to do!
Okay, BrotherMan, here's what you do:
Spend some quality time with your innermost heart and figure out what you really want. Make yourself breathe deeply and find your center. Then whatever you do will be coming from your authentic self.
Then, sit down with each of your loves and share your heart with them. With love, respect and compassion for everyone concerned, be honest and let them know what you need and want.
If you and your primary had agreed to be monogamous, you violated your agreement and her trust by becoming "romantically involved" (as you say) with your OSO, and the three of you will have to work through those issues if the three of you are to have a future. I'm not saying it's impossible, but you didn't do yourself any favors there.
But if you approach the situation now with honesty, respect and compassion for everyone involved, you still have a chance to build lasting relationships here.
