Endings are hard i would say they are almost impossible, so many loose ends to check, plot holes to cover and it's very likely almost nobody will like it 100%.
Theories asisde, any ending you can come up with has always be related to one thing, the main plot, which in this case is the Council/Admin and their objectives and not Asuna/Inoda and Kirito.
To see if the ending pass you always have to consider how this fits with the narrative council/Admin plans which are mental control/domination and merging FOG and IRL in some sort of new reality.
I would bet in 2 possible endings: Kirito goes against the council agenda and this led him to discover about Asuna and Inoda affair in FOG only but since he fight and block the merge he is kept oblivious to IRL cheating as well, and following his on argument "FOG is not real" and everything like the IRL halucinations were because the council but he forgive Asuna and stays with her as long they dont play online anymore, but at the same time she keep fucking Inoda on the side. Oblivious Cuck
Or the NTS cuck he play along with the admin/council proposal of this new reality because he's got corrupted and much in order to what the goddess told him "you should accept because you will make all your friends happy" and he will knew about everything but maybe he will have access to other girls.
