What would you do?

In October of last year, I moved back home to live with my parents after a series of financial issues. To clarify this at an early point, moving back home was their idea, not mine. I had simply driven down to their house to take back the spare key to my apartment so that I could surrender it to the land lord, and they insisted that I move back home as opposed to my plan to live out of my car and stabilize myself financially with a minimum of financial commitments.

Shortly after they invited me to move back home, they began charging me rent in the amount of half my previous apartment rent, and setting household rules which I was expected to follow. I both understood and resented this, as it was my original plan to live out of my car without the financial obligation of rent, and without any "household rules"

I have tried numerous times to leave their house and resume my plan to live out of my car and save the money I would be spending on rent, and be free of my parents household rules, however they are extremely confrontational whenever I try to do so, and tell me I will end up getting "into trouble with the law". In addition, my parents have been very needy in the attention department since I moved back, questioning why I spend so much time alone in my room rather than downstairs with them.

So I ask the question, in this situation, what would you do?

I understand it is not ideal but as the situation stands, why don't you turn it around, you are only paying half the rent you were so are still saving money. You are still living there so something more than there needs keeps you there, otherwise why are you there? Their worry about you being alone all of the time in your room, may not be that they are needy but that they are concerned you are shutting yourself away..
Try talking to them as an adult, they may only want what is best for you and sometimes parents are full on.. Trust me I am a parent, but for the best reasons..
And maybe see things from their perspective..
If all else fails, you still have the option of your car.

There is always a possibility to say alright, maybe there is a reason for all of this which i cannot see right now... I mean how about take few months of Your life and do exactly what they want. Do not be in Your room and be as much as they like with them and do them a company and follow the rules they requested , just lets say two months without anything against it. After that go Your own way, whatever that would be...

Personally? I would be thankful for a roof over my head and parents who are doing only what they think is right to protect me and keep me safe.

The reality is that whether they "insisted" or not, you chose to accept the situation. Unless there was some kind of mandatory court order or you were forced, you chose this alternative.

As for trying to leave, they are clearly concerned for your safety and potential "trouble with the law". And needy? For wanting to spend time with you and being concerned that they feel you're anti social?

What parents would want to see their child homeless and living in a car? Its sounds to me as though they are desperately trying to help you, and dont really know how.
