Is Having Only One Chinchilla Bad?

I only have one chinchilla and do not plan on getting another one any time soon. Is it really that bad for a chinchilla to live alone? I know they are social creatures and in the wild they live in larger groups. My chinchilla gets love and attention everyday and is let out for hours at a time on a daily basis. My boyfriend and I have become almost like "other chinchillas" to her. But are there any certain activities I should be doing with her to make sure she is always happy and never feels lonely?
