While yes, YTA, there's another tradition. With a little something called soul-viewing, you can see their true selves even billions of years down the line. This helps select the ones who will love you no matter what, through thick and thin, and will trust you with their big hearts. After that, you can both become pseudo-dhampirs by performing a ritual involving sage and mugwort upon your wedding night. After you finish the incantations and you both ingest the herbs, chewing them well, you must let her bite you first and drink your blood. Biting her and drinking her blood in return is optional. However, you both will have some vampiric traits which can be easily hidden as well as immunity to sunlight, garlic, holy water, crosses, and silver. Aconite is still a danger, though.
