Second time when I am forced for divorce, still confused?

Hi, I am a working woman in a pvt. company. Though I recently started earning well, there is always job insecurity. My parents are ~80 yrs. of age and 5 sisters, all married. My husband who is a doctor, has recently left his job for further studies. Its being more than 5 yrs. of marriage. My husband is a big liar. He makes stories against his own family to get my sympathy, and then do the same with his family and gets their sympathy. I keep on helping him emotionally and financially, but as he belongs to a rural background, he treats me very badly. Public abuses, not picking up my calls when with his family, insulting my parents in public by making stories against me and not helping me financially or in any way. This forced me to go to family court after living 6 months alone all by myself in a new city. He acted well and this confused me and my family, coz of which we started living together. That time I was earning peanuts, while he took all the house stuffs and disappeared for 6 months. This time he again switched off his phone while in constant touch with his own family. Me and my family know about his college but don't know where he lives. We tried reaching his family who also refused to share any information about him. My parents are planning to meet my in-laws or go to his college, but we are confused if he can use all this as a mental torture to him. Currently I am earning and also ready to support him financially and talk to him to resolve things, but he is unreachable. Though its getting tough, I am confused if I should file any case against him and his family or not? If yes, I don't want divorce but forced to divorce him as he keeps on doing this frequently to make me accept his conditions. Should I file divorce or keep living like this and wait for divorce from his side? As I am so hurt and depressed, I have no plans of marrying again, the only thing that scare me is my private job which is insecure. Should I go for divorce on mutual consent, or ask him for some financial aid? Though no one says anything directly, but he and his family keep on tracking my salary and inquire about it, just to inform, during my initial days of marriage, my in-laws (not husband) were very unhappy for not getting money they desired for and keep mentioning it for more then an year which forced to live in a hostel in same city, while my husband stood with his own family at that moment. I have already suffered a lot, so I just don't want my parents to suffer because of my wrong decision of marrying him. I an still emotionally attached but cannot trust him for anything. Please guide.
