Can I get an uncontested divorce based on abandonment?

Six months ago my husband left our house and did not return. He did not tell me he was leaving and has not contacted me since. I have no idea where he is living now. We do not have any children and the only property we own together is the house I am living in. Can I get a divorce from him based on abandonment? If so, how long does he have to be gone for me to qualify for the divorce? Will the judge be able to transfer the title of the house from our joint names to just my name? How long does the uncontested divorce process usually take? I live in Richmond, Virginia.
