Juni,
Sounds like they got to you about the same time they got to me. I was pregnant with my first child and feeling the insecurity that major changes bring into your life. It was that little blue book that they left with me too. I read the entire book one afternoon and liked some of the things I read- no hellfire, paradise, never having to die, not going to war, etc.
When my husband and I started studying with a young couple our age, the love bombing started. The red flags started appearing also. The blood issue seemed to be based on flimsy logic and a few select scriptures. They convinced me it would never happen probably in my life, so why worry about it?
A lot of other doctrines were never even mentioned in the Bible such as holidays and smoking. More red flags ignored. I also wonder what life would have been like if this 30 year interuption would have never taken place. I do have good relationships with all of my grown children and I am thankful for that. I hope some day they will see the light or more correctly, the red flags they have been ignoring.
