Ross is tough. Isn't he stubborn, bossy, and arrogant? That doesn't seem to fit IxFJ. Not really sure about him...
He strikes me more as whiny & passive than bossy & arrogant. IxFJs can ve VERY stubborn, especially INFJs.
On the show, he seems to turn people off right away because of those qualities, but the people who know him well (the other friends...) like him because he's actually caring & romantic, has some random/interesting knowledge (okay, he's a nerd ), and he's somewhat imaginative.
I think that sounds very IxFJ. I still lean towards ISFJ.
