From your question, I can't tell if your children are grown and live in Jesup or if they are minors and you want to move to Jesup with them. If your children are grown and live in Jesup, I'd ask them to find you a reputable agent who can work with you. Your children know you and will be able to select an agent who is a good match for you.
If you could "buy out" your husband, this might be a viable alternative.
So sorry to hear of your pending divorce.
Definitely speak to an attorney first. Once you have a full understanding of Georgia's laws, then you can move forward. There are a few options you have: 1) sell your home and split the proceeds with your ex, 2) You stay in the house, re-finance and buy him out or 3) He stays in the house and buys you out.
Make sure you know exactly how much is owed on the house and how much homes are selling for in your neighborhood. The state of the market in your area will determine which option is best for you. This is where an agent you can trust will come in and collect that data for you to help in your decision making process.
Good luck with everything. You will make it through this.
