I agree with Scotsman...send a postcard with just a simple I love you and hope all is well.
In the very beginning you say in part: "...any hope that you can come to your senses as far as this religion goes and we can renew our relationship..."Right there where I bolded and underlined...you just lost him. Say that to any JW and it'll put them on the defensive and you know how they get when they feel they or their precious faith are under attack.
You have valid points but if you want to reach him you can't use them, not like this.
