Hi konkreetgurl, welcome! Hopefully, you will find some answers to your questions here, and while some posts are very anti-jw, most are pretty insightful...and that's coming from an active jw.
And I agree that it's best not to tell your jw friend that you visit here. He/she will automatically classify the info here as not worthy of your consideration.
Rather than actually being a cult, some experts consider the jws a "high control group". Whatever the case, your interest in this site is much appreciated. I hope you derive some benefit by visiting here. Best wishes!
