Nice of this "sperm donor" to let you live there for free which was perfectly fine until the guy got tired of you and locked you out and suddenly became the bad guy. I suspect Christmas dinner will be a bit lonely around the old dinner table.
At any rate; what he did was not legal and no, he can't start tossing your things out without a court order granting a dispossessory affidavit (Georgia's version of an eviction). So the question becomes what do you wish to accomplish? Move back in? Be able to enter the property to get your property? If the latter you're likely to accomplish this by contacting your local law enforcement office and explaining the situation and having them accompany you back to the property to accomplish this peacefully. If the former said boyfriend might make some headway sitting down with "sperm donor" and talk nice and attempt to come to some understanding regarding being able to move back in. Something that you haven't posted here set dad off where he was tired of you living rent free on his property. Good luck.
