Annulement of marriage on non consummate ground

Q: Hello I got married as per hindu tradition, but after marriage on first night girl told me that she doesn�t like me and she don�t want to stay with me and would like to pursue her studies and career. I respected her decision and she left my house after three days. Our marriage never got consummated and after three months of this incident we had meeting with family elders in which it was decided that girl and boy should get separated. We documented everything in a 100 Rs stamp paper along with signature of 5 relatives from each side that (1) It was girl and boys decision not to carry on with this marriage (2) we never had any physical relation during these 3 days (3) All the girls belonging were returned and monetary issues like wedding expense got settled by cheque. (4) Although it is case of annulled marriage but neither I can press charges on girl�s family for getting her married to me against her will as they are in our relationship, Nor girl would press any false charges on me. It�s been 10 months now and both parties don�t have any contact with each other. Neither girl nor her family have any objection in me getting married, but they don�t want tag of divorcee for us as we only had only 7 pheras together in name of marriage. The issue now is :- Do I need to legally take divorce from girl even when our marriage was never consummated? Does taking only 7 pheras considered to be marriage even when it is never consummated and not even registered? How can I get this marriage annulled without filling any criminal case against girl or her family? Can this marriage be annulled if both parties agree on this case and how long it would take to get it annulled in court. So Even if I get married again can girl or any third party file case on me in future? What is the way out as my query is not about how to take divorce but how not to go through that procedure as the truth is, two individuals never entered into married life.
