If Duncan was pissed with Courtney,why didn't they just talk out their problems ?

Because they're Duncan and Courtney! Courtney is too stubborn to agree to anything and Duncan is just so arrogant so they both like to win an argument. It usually works itself out somehow.

I think it was because Duncan doesn't know how to man-up and face his problems. I mean, he could've easily told Courtney what was bothering him, did you see how happy she was to see him?! They are madami than capable of working out their problems! But noo, Duncan had to be a wimp and leave when things got difficult. Not only did he leave, but he never gave Courtney a reason to think that he didn't like her anymore! This is why I think Duncan and Gwen won't last. They have both run away from their relationships when they got hard. Gwen ran away from her and Trent's relationship when it got hard. Duncan ran away from him and Courtney's relationship when it got hard. They run away from their problems -___- So I'm betting that if things get too hard in THEIR relationship, they'll break up too!

Why dn't he do the logical thing and break up with Courtney first. I guesws will never knew what happened to Duncan brain when he was gone, lol.

He probobly thought she wasnt worth that, and wanted to make her sad/angry

he was too much of a wimp.

Maybe because he knew Courtney was gonna be angry at him and Gwen. I guess it just wont work out... but I want it to. Why cant they just forget all about this? Courtney is my paborito character, but she just has some anger issues.
