Filing divorce in Singapore while Divorce is ongoing in India

Hi, I have been living on Employment Pass in Singapore for 8 years and married for close to 3 years. My wife usually picksup fight in everything, for reasons like going to my sister's home (they are PR here for 8 years), bringing my parents for a short trip from India, watching a TV channel that she don't like, etc. She attended several interviews in Singapore but cannot find job and not willing to be a mom as well (she kept avoiding having sex to avoid getting pregnant) she tried to find job in India without my knowledge and kept asking me to allow her to go back to India to work for which I asked her to keep learning and find a suitable job in Singapore itself. After plenty of quarrel on this she created a scene and asked her parents to book tickets for her to go back to India (finally I booked the tickets and dropped her in airport) and I thought it is going to be a short separation to realise each other but her plan is to work in India and not returning back. She joined a new job there without informing me or anyone from my family and when we came to know this and met her family to console her and asking her to rejoin me in Singapore they threatened to call police if we tried to take her back. Finally she rejoined me after 4 months of working in India with the effort of few family members and a hired family counceller. Her main aim was to not have a career gap as she can find job easily in India. Luckily she got a job in Singapore after she returned and worked for about 7 months and one fine day after I left for office she left the house with her hand luggage and landed in India without informing me or anyone in my family. We came to know where she was only after a day when her dad messaged my dad. She transferred all her money that she earned here to her account maintaned by her dad in India and she never informed me that her job contract has ended (as usually contracts will be signed for 1 year and employer can choose the number of months based on requirement). That's it, I went to India and filed divorce against her (6 months old now) for which she replied with maintenance case (5 months old now) claiming half of my Singapore salary (3/4 of it is expenses in Singapore itself) and then came Restitution (5 months old now). Recently, she sent Domestic violence case as well. One of my friend recommended of filing divorce in Singapore which is quite faster compared to India. I will be completing my 3 years of marriage soon to file for it. But I have few questions related to it, 1. Can I file a divorce in a foreign country while it is still ongoing in India? 2. If I get the divorce in the ground of unreasonable behavior (as she gets triggerred for each and every action) can this be considered as the divorce as per ground of cruelty as per Indian law and dissolve the cases in India? 3. If it can dissolve them, what happens to DV, MC and Restitution filed by her?
