Steffe, it is hard for parents to let go of their children. That support they have been giving you, is the only form of control that they have left over you. They offer to pay your phone as a way to say we want you to stay in touch - at least that is what they try to tell themselves. They pay your car insurance as a way of saying I want you to be safe - also what they tell you and themselves. Some parents have trouble knowing the difference between being in your life and controlling your life. I know because I had issues with it when I was leaving the home. That financial help is coming with a pretty big emotional price tag. If I were you and if I had the resources, I would cut the financial tie as soon as possible. They can not force you to take their money. You may find that your complete financial independence changes the relationship in a good way. They will then know that they can not control you and the relationship will go to a different level - one of respect and one in which you treat each other as adults, rather than parent and child. As long as they provide financial support, they will feel that they have the right to exert some control.
Glad to hear about your landlord. Good luck!
