No response from the Spouse and her family members since a week.

Hi All, Both of us are divorcees. However, we got married again in this August 2017. Both are employees and staying away from home. She is staying in Chennai which is at 3hrs travel distance by Bus and approximately same time even by Train also. But, I am working at my in-laws place (Tirupati) and staying in company provided home and not staying with them. As, I was working at Tirupati, her father has initiated the marriage talks with us. Prior marriage, I have clearly informed them that, I can't give a commitment to either stay at the current place / Chennai as I have been placed here on deputation. She and her parents agreed that she will move with me whenever, I got transferred from Tirupati. Once, in a month, I go to Chennai to meet her (as I will get Second Saturday holiday). But for her every Saturday and Sunday is holiday and has never come to Tirupati, citing her official assignments. On the second Saturday before Diwali, I went to Chennai and found that she is sick. I suggested her that we should see a Doctor. She refused for that and asked that I will see a Doctor at my parent's place (Tirupati). However, I dropped her at my parent's place and travelled to my native place to visit my lonely widowed mother. Since, then I didn't receive any call / response to any call from my Wife. Once, my mother-in-law responded and said that my wife is recovered and resumed at office. Even, I got the same response from my father-in-law too. Further, neither my wife nor my in-laws are keen to register our marriage. Please let me know what should I do ?
