We are/ were not part of the world. The world is permitted friendship. Unless you join another religion that has many "social" activities and groups, it is a long journey ahead.
Funny I have never in my entire life had a JW close or best friend and I was raised JW. I have had and still have many "daily acqaintances". I think it is part of the conditions that we endure in the "be not" rhetoric, the fact that friends snitch to elders, and that worldly associations are frowned, if not forbidden. Besides who had time for friendship when there was all that reading. Were any of you EX-JWs, really friends with your co-KH members or just FS buddies? A means to an end.
I also have to take responsibility too, I like my space and letting people in is scary because as a JW or Ex-Jw that means you are different, there may be rejection or judgment.
