Hi LonelyL, no, that doesn't make you a freak. I am turning 40 this year, and never had the experience of someone ever loving me, getting married is an abstract concept that I read about and that I suspect will not happen in this life. And that in spite of leaving home when I was 18, and never going back for more than some months.
Living with one's parents becomes a problem in some way, that is: a) if the relationship with parents is keeping one's from expressing themselves.
I explain: one of my uncles lived with his parents until he was 60 but he was like a child, always quarrelling with his mother, hating her but also being totally dependent, I guess if one manages to keep one's independence living with parents is not a problem,
unless
b) one wants to party, and/or get laid, then living with the parents is really a downside, unless one wants to be really disrespectful.
It's not like moving out of the family's house makes one automatically get a life, you can already start trying putting yourself out there, but if you feel that living with your parents somehow affects your personality in a negative way, consider moving or finding a very personal space. But yes, the eventual problem is not at all living with one's parents, but rather the relationship with them, so if that is OK and they are happy that you have your own life and you have your space without the hassle and the expense, then it's great.
