False 498A case , I need my child

Hello sir/Madam I went to Germany for one month business trip. During that time My mother & wife quarreled each other. After three days My wife went to their parents home along with my son( aged 11 months ) in midnight. without informing us, I called & spoke to her several times , Also sent my father & relatives to convence her. But there is no use. Finally I sent one lawyer notice for re-joining. After that their relatives came to my home almost 25 people, they all discussed & finally they accepted that mistake is from my wife only. There is no problem from me also from my mother. Also they told me that they will sent her back in December 3rd week. She only assuming everything blindly, I am planning to celebrate my son first birthday on Jan-1 Now she is telling that, she is not interested to rejoin marriage life. She will not allow my son for the birthday. Our marriage happened 2012 Feb. We both are from Andhra Pradesh, staying in BANGALORE from beginning. She is from poor family, so even for marriage also I only supported financially. They were not in a position to spend for marriage, so we did marriage at my home only with 5 lak. I also brought gold for my wife worth of 6.5 lakh. I have all the details also. (To be frank they had given 4 lak for arrangements/dowry/gold what ever they may call) Both of us 30yrs old, I am earning 60,000 per month working in a private company. I have no property on my name. But my father had own land (purchased 25yrs back) before marriage she was doing job for 10,000. She resigned before marriage. Not doing any job now? After marriage we had 4 continues miss abortions I spent all the money from my pocket. Even for son birth I spent 1 lak for delivery charges. Now I would like to know few things from you. 1. Am I allowed to take my son, from wife for first Birthday (I am asking her to join, if she is not accepting), I don't want separate them, I will return after the birthday. 2. Is it possible for her to file kidnapping case on me? 3. I came to know that, she is planning to file dowry harassment case against my mother (may be on me also) Is it really possible fake cases like that, without any proofs? 4. Suppose if she files a case do I need to pay maintanence? (I am not interested for divorce, I don't want to spoil my son future) 5. Is it possible for my wife to applying & obtaining divorce with my acceptance? 6. If at all there is chance for divorce I don't want to leave my son. (I am ready to pay her maintenance etc..., But I want my son with me) 7. She is planning to take money from me, for Thier parents maintenance also. (I don't know why I need to pay for them) 8. Is it possible for her to file case in Andhra, if so do I need to travel everytime from Bangalore? After all these things, now I really got very bad impression on my wife. I hope I may not continue smoothly like before. But I am only worrying about my son. Please guide me what else I can do.
