Hello, Anonymous.
This is going to be a VERY fact-specific case. It is generally very difficult to get paternity reversed unless there is another man who will be stepping up as the acknowledged father.
Unfortunately, I can't answer much to this question right now without many more facts, largely due to the complexity of a case like this.
The best I can tell you, I'm afraid, is to call an attorney in your area and discuss the case in detail with them to figure out your options.
