It appears that all three of you have reached the point where you understand your own issues, have taken responsibility for them, and can thus accept each others' issues and be supportive while allowing each to attend to his own matters. Taking care of all parts of the relationship (web) hinges on that, I think.
A fully functional relationship involves taking care of You, Me, and Us. In poly situations that gets extended to taking care of You, Me, Us, Other You, Other Us (however many times necessary), and All of Us (the whole shootin' match). If everybody involved is taking care of all of those entities, then all is well. From what you described, that was happening on that day.
