I was never a JW but you should press my avatar and read my introduction to this forum. My advice to you RUN, do not look back. Very sorry for the heartache this young lady has caused you but you can find much better women in the real world who do not come with CULT ties. If I read your story correctly you have children already the WT HATES children. Read about the child abuse, ARC, pedophile issues, and go through this site and read some of the comments about the children's cartoon Sophia and Caleb that WT produces for the kids total emotional abuse.
Go to JWFACTS research this religion before you do anymore studies, these people LIE, LIE, LIE, I am totally convinced that they would not know the truth if it hit them in the face.
Welcome to the forum, here you are among friends trust all of us, those at the KH are NOT your friends they will stab you in your back the minute you turn around. Think about that statement someone from your girlfriend's congregation turned her in to the Elders when they saw you to together and she got disfellowshiped. Now how loving is that? Do you want to live a live being watched all the time by every member of the congregation?
