A very warm welcome to you, 'not a jw'.
You are on a very steep learning curve regarding the JW's and their beliefs and practices. I remember in 1952 asking the same questions as you do now, my wife also said the same as yours! I have managed to just live with the JW's since then; many can not succeed at that.
The JW's are NOT the people they make out to be, they live in 'cloud Cuckoo land'.
Keep reading the posts here with some discernment and you will learn a great deal from people who have been through your experience.
Best of luck with your journey.
