Questions on ex-party divorce.

I got married in Aug 2014 and I have a son, we had many issues which was not resolved in my marriage life and my wife left to her parents house, I got many life treat’s with my in-laws and I have relocated to other city. After much consideration I finally I have decided to get divorce and I have applied for divorce in 2016 under grounds of cruelty, after my wife received the court notice my wife attended the court initially and judge gave us counseling and asked us to compromise and gave us 2 months time, even after judge counseling things didn’t went well and later when judge asked her to file the counter she stoped coming to court for around 3-4 times/dates, then family court judge asked for x-party evidence and gave an ex-party orders on 26th Aug 2017 which says "Order pronounced in the open court, In result petition allowed without cost, dissolving the marriage of petitioner with respondent which was solemnized 30/8/2014.". The current status of the case says 'Uncontested - Allowed'. I do not want to get reunion with her again in my life, I love my son and I am missing him alot, I feel lost in my life and staying away from my family and hiding my face in front of my relatives and society in different city since 2 years because of my wife and her parents. Questions: 1. Is this divorce legally valid, Am I legally divorced with my wife now? 2. Since I have filed divorced she is not in contact with me, if she comes to know that court has granted ex-party divorce what will be her options to legally trouble me again? Now can she now file any false cases against me? 3. If she and kid wants support and need maintenance, I am ready to pay the maintenance to kid, but will it effect the divorce as court will ask to stay/continue with her or still I can be legally separated with this divorce orders? 4. If she asks me about ex-party divorce what answer I should give her, how should I respond to her? 5. After how many days can I again get married after ex-party orders? If I get married again, is there a chance my ex-wife will make a legal issue if she comes to know about it? 6. What is the best advice for me to completely get rid of my wife's new-sense in coming future and to be safe by not running around courts in my life?
