My husband is having an affair and I have had enough. What can I do to have him move out the house, he refuse to do so on his own.

Georgia does not have legal separation, so you are pretty limited to filing for divorce. The house is part his, so you can't just force him to leave without some sort of legal proceeding. You need to file and request a temporary hearing. At that hearing you need to explain to the judge why you deserve to stay in the house and he should be forced to leave. These sort of actions require a lawyer with experience. I would not recommend trying to file it on your own. I would consult the lawyers.com directory and find an attorney that is based in the county you live in.
