My girlfriend and I have been together for about 3 years, living together over 2 years. She is starting to hint about marriage and kids. I knew this would eventually happen, especially because her family is religious and they frown on us "shacking up," as her dad apparently calls it. I love her deeply and she is great, but I have never told her about my AB side and feel guilty getting married without being completely honest with her. Frankly, marriage in general kind of scares me. Advice???
