Legal Rights of 2nd Marriage

Hi Sir I am Usha [42yrs], from Bangalore I was married in 2002, due to many mis-interpretations separated after 3 yrs and have got legally divorced. Have a girl child of 17yrs (present) I was working and living an independent life for about 10 yrs. In 2015, met a person through matrimony site, who was separated but not legally divorced having a son of same age as my daughter. With communication interactions for about 6 months, we mutually agreed upon accepting children and taking life towards 2nd marriage. We got married in 2015, and living together with children. Though he is not legally divorced, I accepted with trust & emotionally believing in his talks. Life was going very smoothly, purchased new flat, I couldn't continue with my job as I was finding it difficult in taking care of children, his needs, house maintenances & my things. From past 6+ years, most of the things are being ok, but for any small dispute, in the family he says Get out of my home, which hurts me so much in spite of being so committed and dedicated to the relationship, since he has spent money on the house, he says its mine, you can leave the house. So, would like to know are there any legal point that can support my case. Your Inputs will really help to safe guard myself & my daughter Thanking you Sir Regards Usha
