Marriage

In 2014 I get married to a southindian guy (Intercaste marriage).All is well till Mar'2017.I too have a baby of 2.5yr old.After that my in-laws comes very frequently to visit us and I found lot of changes in husband's behavior and due to that we have disputes.Since I get pregnant I was staying at my mother's house which is near to my office.As the baby grows I found it will be good if my husband also stays near to my mother's house, so that I can take care of them as well and give a visit to my kid anytime during my office hours and it will make life easy.My husband don't like my approach towards comfort zone.Whenever I went to my husband's house , he start fighting for minor issues and always says I am going for suicide even he says these to kids aswell. I am helpless now, whatever I do or try to make this relationship strong again , he is always taking this to -ve side.I have taken responsibility of my parents, is there anywhere mentioned that a girl cant take the responsibility of parents after marriage ? Now, my husband is undergoing a surgery and admitted to hospital but I have not been informed where he is admitted. No-one from in-laws are picking my call.Is that right ?
