Michael,
No harm meant toward your buddy....he sounds like an ass. He is "bait and switch." The bait is his friendship and the switch is you becomming a JW: would boost his, already, inflated ego a lot...
You don't need THIS discussion: you need to widen your circle of friends. You need some people to broden your opportunities of relationships. The JWs are the LAST people to do this with: total fakery.
I would recommend reaching out in your area by getting involved with some "help your neighbor" groups. You seem, in your posts, real sincere and like-able. Reach out to others. Perhaps, you are a bit reserved...shy....
It would require effort and risk :well worth both for friendships that are built on MUTUAL respect and admiration.
That is my take.
Just tell your buddy you want to put your study "on hold." Back off the religious discussions. Reach out in other directions...there are so, so many.
Spend some time on this board. Continue your spirital Journey, not just with the JWs, but, Christianity generally.
I'm going to bed.....
Take care,
V
