I wondered because I thnk most of us were glad he finally listened!
I agree that the most important relationship is the one formed by a couple, but it woud be a red flag for me if the person I was interested in wasn't liked by others - even though it IS a stressful situation. The other girls seem to at least get along. Thinking back to AshLee telling Tierra that she wouldn't respond to a simple "good morning?" I can see why the other girls thought she was rude.
I'm sure that she wasn't as bad as she was portrayed, but I believe her social skills and her grasp of common courtesy were lacking.
