A recent addition to the Asylgesetz, §8(1c), says that authorities such as the police, border control, the foreigner's authority, or the social welfare office must notify the Bundesamt für Migration und Flüchtlinge (BAMF) if you're travelling home. BAMF then has to decide again about your refugee status.
Your refugee status will be lost if you settle in your home country ("sich dort niedergelassen hat"), among other reasons, see §72(1a) Asylgesetz. If you're only going home for a short visit, there might be a chance that you can keep your refugee status and return.
As many others have written, seek professional legal advice before you decide to visit your home country.
(I'm no legal expert. My personal advice would be: don't go, unless your reason to travel is far more compelling than the reasons why you're seeking refuge. If you're a religious person, try to pray for your loved one where you are.)
