Omg, I think this redefined the word “complex”!
So, how does this relationship actually work? Do you all have active relationships with each other?
Fascinating!
I doubt you will get much advice on bringing up a child within such a relationship but you never know. The thing is what role(s) will you play for the child? Clarity is critical there I think.
Wishing you lots of luck!

People find this hard to understand, but the dynamic is just a man with two girlfriends, if you put aside my birth gender it becomes much more simple

Before Daniel, it was just my GF and myself for 5 years, we had a difficult relationship at times and my gender issues caused a lot of intimacy problems, compounded by the fact that I don't think I ever fully developed where it might be expected.
My GF felt like she was the problem and that made me feel terrible, she suggested we try a poly relationship, she had a handful of dates, but I eventually met our BF, he's a bit of an "admirer" so he found me, he's divorced with no children and he's 46, 5 years older than me, and 11 older than her.
With regard to being "active" with eachother, we love eachother very much, we are "active" together in many ways, but to avoid being crude he is the man in the relationship and has been for the last 3 years.
We've talked about roles, but I don't think we'll know until it happens, I think or hope it will develop naturally as it does with all new parents. Except there will be 3 of us sharing all the responsibilities.
The more we've talked about all this, the less anxious I feel. I think I just had a lot of irrational thoughts and crazy ideas.
