Georgia does not recognize common law marriage anymore. Therefore, living together does not create any rights or obligations between the parties. If you do not have any legal right to the home, such as your name on the title or lease, and your name is not on the vehicle title or registration, then he can eventually take those from you. However, you have the same right to remain in the home as a tenant who must be given notice and a legal right to contest any eviction. He cannot just put you out of the home. If he threatens you with harm, you should take out a TPO immediately.
I am exclusively a family law attorney, practicing primarily in the metro Atlanta, Georgia trial courts. However, I handle appeals from anywhere in Georgia.
The fact that you have been living together, and he has been supporting you, does not mean that he is obligated to continue supporting you. You have no rights to avail yourself of divorce laws unless you are legally married.
You cannot have your vehicle legally taken away by anyone other than a legal creditor. However, before you can have the vehicle returned to you (or be awarded the value of the vehicle), you would have to be able to prove that it is "yours". This will depend on the name(s) on the title and/or the history of payments.
No one can be put out of their legal residence without having first been legally evicted. The fact that you have been listing the residence as your primary home makes it your legal residence. Therefore, your partner would have to evict you in order to put you out. Or if you've already been put out, you would have a valid claim against your partner for an illegal eviction.

The above answer is a general explanation of legal rights and procedures. It does not constitute legal advice. Nor does it establish an attorney-client relationship between the individual posting the question and the attorney providing the answer.
