I always liked Xander and Cordelia...as for Xander and Willow...I always had this theory that friends and lovers never mix...Of course, this is all based on my attempts to get more involved with all my friends(who are girls). All of them just ended up into a bitterness and depression. Besides, who is Xander going to complain to when Cordelia/Anya treats him like garbage--Willow.
