Welcome! As you have no doubt noticed by now, this forum is far from being the official web site of the Watchtower Bible and Tract Society (that being the corporate name of the religious group whose members are called Jehovah's Witnesses).
There are several good resources on the internet for learning about the Witness religion. I recommend freeminds.org, starting with the doctrine section. Since you're becoming romantically involved with a witness, also be sure to read the sociology section.
