"... sometimes I smirk and think that God gave me exactly what I asked for: to go all the way. "   Sounds like you went all the way out the back door there.  :)  So God gave you what you wanted.   Just kidding.

These are wonderful questions and observations.  I too have had an experience with church leadership that was hard and difficult to interpret as far as the end-meaning.  What I can say ultimately was that regardless of what happened and how others reacted, be it poorly or not, the greatest gift was in what I learned through the experience.  

You could say that "God" taught me these things, or you could say i learned a lot from this experience with or without God, but ultimately I did change.  I did grow up a bit, and I did realize that the thing I thought I really wanted the most, I didn't really want.  It brought me to a better place.  

So to answer your questions, of course I create God in my own image on a regular basis.  I Am quite good at it, by the way, and then something comes along and happens to me or someone I love, and God ruins my image of him with his own and I have to change the way I think about God-- I have to redefine who God is in my mind.  So my God is a conglomeration of my own caricatures, my own image and the reality that is God as revealed to me on a recurring basis.

As far as does God play the evil genie?  For me, I don't like to imagine that God is that way.   I think it comes off as a bit vindictive, and if I cannot trust God to at least be genuine with me, then I don't know that I can trust God.  But I think that definitely we are real good at screwing up things entirely on our own.  And of course:

"Where two or more are gathered in my name...  there are twice as many F#%ked up situations, mistakes, damage done by good intentions and so forth...." (Book of Me 1:9)
