I can really relate. If I have personal space at home I am a very social person. But if people are on top of me in my home I just want to get away from people all the time. Living alone is bliss and I can be a better friend, coworker, or partner. I also find what job someone has can affect the balance. If I have to talk to people all day then when I come home I don't want people in my space. Its great you realized what makes you happy and you're only 30.
