Good for you! I have two male partners, although we don't all live together. I didn't go looking for the relationship with Nat to turn into a life partner situation, but I'm glad that it turned out that way and I understand a lot of what you are saying here.

In my local FB polyamory group there is a throuple where the men live in houses next door to each other and the woman and her children (with both men) go back and forth between the two. They are all raising the kids together and seem really happy. Take the complexities of children out of the equation and it seems like it would be even nicer. Best of luck to you!
