Newlywed,
About God forgiving you. YES. Even the church recognizes divorce for legitimate reasons (physcial abuse/mental abuse) They tend not to recognize the "oh i dont love you and im bored etc" type.
In this case talk to your minister/priest/rabbi. I do not believe that you have anything to repent for and I bet your advisor agrees. Repenting is asking for the forgivness of sins. My favorite expression that even can help the alcoholic??
"God realizes the difference between weakness and wickedness".....peace to you
