I began researching about Bill W and cannot believe what I found. He was basically a sex addict, used LSD (even wanted everyone in AA to use LSD), came up with the 12 steps on hallucinogenic drugs in the hospital and ect.
Bill was a flawed human being. Having said that I would say he had marital fidelity issues and used LSD. The rest of that there is just no evidence of ever happening or it is completely false. I hope you didn't use the Orange Papers as your source on Bill W or anything AA, they are not exactly unbiased.
All that said, the chapter "to wives" is dated. Take what you can and leave the rest. Better yet, assuming you are still working on the relationship, ask your AH what he expected you to get from that chapter, and discuss it. Alanon would be great too.
Keep coming back, there is a lot of support here.
