Hi Alex_Am. You are in love with a beautiful person with a lovely personality. I can completely understand that. I am a mother of a twenty year old daughter whom I love with all my heart. My greatest wish has always been for her happiness. I naturally don't want her to suffer terrible emotional pain, but it is inevitable I'm afraid, that's human life. I have just tried to tell her everything I know about life and also teach her to think for herself so she can maximise the happiness and minimise the pain.
So that's why I worry about you Alex. I know breaking up with your girlfriend will cause you pain but it will cause you even worse pain to join this cult. It ruined my young life, I don't want it to ruin yours.
It's not just a normal religion, it's abusive and it damages people. It's a good sign your girlfriend is dating outside of the religion, but do her parents know? Are you just meeting at school? Does she strongly believe or does she talk about leaving?
I know it's hard but if you were my son I would say please don't cause yourself pain for many years to come by marrying in to this cult. If you then have children you will be trapped. An outsider with your whole family being indoctrinated and looking at you as a bad person unless you pretend to believe every word. You don't want to live like that do you? I would hate my daughter to live like that.
