As a Side Note: I chose not to include "Willow choosing Tara" as an option because I thought that was a whole other question. :)

Right. Willow had already established a relationship with Tara. However, I never really felt that the whole mess with Veruca was really his fault, It was his wolf and he barely had a grasp on the creatures actions, it being one of the reasons he left when he did as he feared hurting Willow and wanted to attempt some help controlling it.

However, infidelity does hurt and so does the loss of the person you love.

What Oz did was wrong but you have to remember it wasn't entirely his fault!! He had no control over his wolfside and all he wanted was to prevent Veruca from killing anyone. Willow on the other had kept purposely sneaking around with Xander behind Oz's back and maybe would've ended up in bed with him eventually if Oz hadn't caught them when he did. So I'm siding with wolf-boy on this as he did get the bitter end of the stick in the end. BTW I hated Tara, she was conpletely all wrong for Williow though I wasn't happy with her change in character either:/ Yes it hurt when he left but I think Willow not waiting for the one she loved and moving on very quickly hurt wayyyyyyy more!!!

Actually, I don't think it was anything to do with Xander. It was her rejecting Oz after he'd gone away to get better for her.

I nearly couldn't choose they both wounded eachother but I have to say with xander and willow, Coridia was the most wounded. Oz didn't have control but he still wanted Veruca more than Willow and he didn't even tell willow the truth and didn't tell willow that he was planing on caging Veruca in with him

Oz because, Willow was so devastated, she near got herself ran over by a car, till Riley saved her. Most wounded
