From all the comments, it seems like the norm to not have all the friends you want...and to enjoy being alone in a way. I wonder if this has to do with what we have all been through? (Having "friends" all around, then losing them all) Or maybe that is how most people feel?? It only takes being screwed over by a supposed good friend to lose the desire to do that again.
I am glad to see others who feel their significant other is their best friend too. I worry that I may be strange that way, but, I feel lucky to have him.....at least I have 1 friend!!
