How much longer should I stay at home?

If you live in your parents house and you do not pay your fair share of the bills then you are living there as their child and must obey their rules. It sounds like your Dad is upset that you spend your money on piercings, going out, and tatts but not on the important adult stuff (bills).

You should move out. You shouldn’t be living off from anyone else (friends included). Get a second job and a real roommate. Find a way to make it on your own or accept the fact that your not as mature as want to believe you are.

If you’re living with your parents, I think it’s only appropriate you live by their rules, seeing as they’re kind enough to take you back in and all, and yes, you should have to pay some of the bills. You have a problem with it? Yes you should move out. I wouldn’t recommend living with a boyfriend until you’re completely confident in your relationship and have known each other a while, if you can’t afford to live alone, move out with a friend and get a place together, I’m sure if you both have jobs you’d be able to manage the bills if you spent your money wisely.
