I have a similar situation, but if I had to live with my parents my mom would be happy at least. She likes parenting, and she would love to have me or my sisters around to parent. She is always planning her visits months in advance. Though, here is a story I heard from a co-worker years ago. He said his brother retired at age 40. How did his brother accomplish this? Well the brother lived with the parents until he was 40. The brother had a job and instead of spending his money the brother saved every penny. Then once his nest egg was complete the brother moved out and retired from the world. So that is something to think about. Of course if your parents are going to charge you stranger prices for rent and stuff you should not waste your time.
another thing to do would be to figure out why they want you to stay. I have a friend, who flunked out of college and had to move home. He had to get a job and because he helped with the bills the family did not lose their house. Granted once things stabalized with him and his family he was allowed to stop paying into the house.
So maybe think about stuff like that. I am not sure if the parents are truly toxic but if you can work out some better deal than living alone and can find the patience to tolerate them. Well it could be good for your perspective financial future. Then again, when it comes to romantic relationships nothing will annoy or turn someone off more than going back to your parents house. So there are things to consider.
