Are two chinchillas better than one?

I've heard some chinchillas are more social than others, but is it better to have two? I have one year old male who seems social but I feel bad leaving him alone. I had thought about adopting another chinchilla to keep him company, but I wasn't sure if he would be upset I was caring for another chinchilla too. I want what's best for him. Will another male chinchilla keep him from getting lonely when I'm away? Please tell me the pros and cons. If it's best to leave him without a buddy then I won't adopt another. I don't want him to feel my love is divided between himself and another chin
thanks
