You must be thankful to God for maneuvering matters for you to get out of JWs, God’s false friend who dishonor Him saying God felt CHALLENGED by Satan and so on….., hence leaving JWs is not equal to leaving Jehovah.

Regarding the use of God’s name:
We have two standards:
1) Jesus used more affectionate form: FATHER
2) Strongest tradition of calling our own fleshly father as FATHER,
Imagine the awkwardness if Malia or Sasha calls her daddy: Father Obama!

You seem to be confused with what MEN have written in the Bible as what God Himself has done it. The very fact that God does not bother what people write even in disparaging way about Him is the greatest proof that He did not treat this book as belonging to HIM. If He had some book, He will definitely protect it from having in it any mention belittling Him!
