You are welcome.
And for what it is worth?
On a selfish note, it would be easier for me if it was only one guy to adjust to.
I don't think that is "selfish." That's just the reality of the situation. Juggling a 3 people poly thing would be less people (and mini relationships among those people) than juggling a 4 people poly thing.
is what it is.
A polyship is made of all the mini relationships inside it. For the polyship at large to be healthy? All the mini relationships within have to be reasonably ok.
Hang in there.
