I am polyamorous and already have a long-term partner. She has a family with kids but does not want more. I respect that. While I love her kids to death, I still want to be a father of my own, in whatever form that may be: co-parenting, adoption. Eventually, I would love her kids and my kid(s) to grow together.

Preferably, I would be the biological father but I am open to alternatives.
I would also prefer to have a romantic relationship but am open to a platonic co-parenting relationship as well.

My best friend and I were discussing platonic co-parenting and this opened a new world.
