It's a process..
Philosophically, I "left" at least a long time before the Maschiach Shlita's timely death. I don't remember the date or "moment". I always had doubts and questions. I wasn't born into a Chabad family (mafdal) - I ran away from home at age 14 to join Chabad in Lod (I’ve been donning rabaynu tam's since my bar-mitzvah). At some point my father (a physicist) gave me a list of questions, such as "why be religious?" For years I suppressed those questions just by delving deeper and deeper into Chasidut .. sitting and pondering "samech vov" (if that means something to you) for 6 hours straight.. so for years those questions didn't bother me consciously. But they were there, unconsciously.. and the unconscious is a lot more powerful than the conscious mind. At some point, I think in the middle of 1991, I began considering those questions seriously, and the more I thought about them, the less sure I became. I realized that I myself didn’t really believe in the answers I’d give people while I was doing 'mivtsoim'. I’m too honest to accept bullshit, especially when it comes from me. In 1993 I read anything I could find on every possible angle on religion, and debated the topics with several of my apikorsishe friends (who simply didn't have the balls to get up and leave) until one day I went over the 13 Irakay Emuna, one by one, and checked to see whether I believe in any of them. When I finished the list, I realized that, no, I don't believe in any of them, and from there the step to stopping all religious practices was fairly short. I remember the first time I wrote on Shabbat. I was writing my journal, lying on the bed in my dorm room, just writing, and I noticed that it was effortless, just like writing on any other day. I remembered reading stories about chozrim besheelah who felt disturbed, fear, guilt etc., when doing the first "sin", and I was happy that I was different. I didn't feel that I "achieved" something, nor did I feel fear or guilt. I've "erased" some of my religious beliefs so well, that I didn't have any emotional response at all. It was something of a test for me, a barometer to see for myself, on an emotional level not just intellectual, where I was. I felt congruent with it all, and since I was still a chabadnik at the time, where everything first starts with the intellect and trickles down to the emotions and practice, I know that since my intellect no longer believed in it, and my emotions were no long attached, that it’s now time to move to the practice, and I stopped keeping all the mitzvoth, while still keeping my external appearance. Shortly thereafter, I flew to Colorado, and I said adios to 770 and my friends, and left, never to return. At the airport, after I checked in but before the flight, I shaved my beard in the men's room. When I finished, I didn't recognize the guy looking at me in the mirror. It was a very powerful moment, a moment that I've taken with me into my life right now. Whenever I catch myself thinking that I can't do this or that, I remember the way I USED to be and the way I am NOW, and know that I CAN do whatever I set my mind to.. Was this answer short enough for you? As to the other stuff - I'm 32, not married, and as far as I know I don't have any kids. And now it's your turn to share something of yourself..
