I'm going with yes, though immature.
Xander's attempted revenge in BBB was to make Cordelia feel the same pain (can't eat, sleep, breathe, and the hell of heartbreak) he did, which was the pain caused by love. It was very immature (though something a great many adults would do if they thought they could), but it was still love. If it was purely ego that drove Xander to try his revenge in BBB then he wouldn't have put himself in danger to save her.
And Xander has a surprisingly mature and selfless moment when he buys Cordelia that dress, something that would've had been very hard for him to do financially (assuming real world finances anyway, rather than the bizarre world of Buffyverse finances) and shows genuine love (not necessarily the romantic kind, mind you) as opposed to trying to get another chance (or just get into her pants--though given Xander's cringe-worthy words over his sexual encounter with Faith, it shows he confuses the erotic with the more romantic, but plenty of men and women who are adults do the same). I know it's hard for many here to understand, but splurging like that is not easy for someone like Xander and was a genuinely good, selfless moment on his part that also reveals genuine (non-romantic) love.
And his remorse seems as genuine as Willow's as well. And no, I'm not going to give Willow a pass while saying Xander doing the same exact thing means love can't be in the picture. And frankly Oz would've been just as right to kick Willow to the curb as Cordelia did Xander (that he didn't makes me wonder if Willow wasn't already dabbling in mind influencing spells even back then since she obviously did other magic stuff "off screen"), and I doubt Willow would've done anything noble and selfless as Xander did after that wasn't trying to manipulate Oz into taking her back. Just to be clear, I do think Cordelia was right to kick Xander to the curb, but that doesn't mean Xander didn't love her.
