I have to agree with DH. You are (literally) asking to be manipulated. People of this mental state are vulnerable to high control groups that promise to make everything better.
For example, your friend offered what you believe to be a convincing argument, i.e Jehovah?s Spirit is gained through meeting attendance, without any mention of the proof of this claim. Since meeting attendance is so pivotal to salvation, surely it is explained in great detail in scripture - right? Certainly, Jesus and the Apostles would not be so incompetent to have left this out. Surely your friend isn?t hanging his entire argument on "don't forsake the gathering of yourselves together" - correct? Do you recall the Bible chapters that explain the Holy Spirit's dependence on meeting attendance? If so please post them. My guess is that since this correlation is found nowhere in scripture, your friend can only cut-and-paste scriptures together, along with healthy doses of "reasoning" to come to this conclusion. Recall this technique has gotten JW's in all sorts of dilemmas from Pyramidology to Doomsday.
If you are going back at least admit to yourself why you are doing so. It doesn't sound like you are returning because of a conclusive study of the evidence. It sounds like you desire the social rewards of returning to the fold. You will return as a "prodigal son", welcomed, praised and "love bombed" by all (at least for the time being). You will instantly gain psuedo-friends (contingent, of course, on you membership). You will hear comforting sermons reassuring your righteous decision.
I would say you are only postponing disappointment. Seek real friends, not conditional one's. Find real meaning in life, not a well-sold story. And most importantly, take control of your life's direction -don't delegate this to others.
