I had always considered myself extraverted but recently I have been shifting towards a more introverted character. Different things happend in different stages of life. That does not mean I want to be alone all the time. I still like company, I still like being with my partner and friends and family. It's just that I need some alone time every once in a while.

If It were to be alone all the time I'd become lonely and miserable. I think many introverts (if you want to put people into stereotypes to begin with) are like this. But not everyone. It's more of a fluid scale rather than a very binary thing.
