I am married female of age 37. I married at the age of 26. After 1 n half year of marriage we were staying separetely for our own jobs. He was little possessive at the beginning. I thought it was normal but it created lots of problem later. The problem started after 3 yrs of our marriage as his possessiveness was increasing day by day. He used to call me with in the interval of 30 minutes to check whether I was in room or outside, he used to listen my background sound rather than my voice. I tried to talk with him several times but he always say sorry I will not repeat again, later he behaves the same. I told him he should trust me otherwise there is no meaning of relation. I feel like its his behavior or his mindset which can't be changed. He starts quarreling if I talk to any of my male friends or relatives or if I go out with my friends. It's been 11 years of our marriage and I am trying to make him understand that we should have belief in each other since 8 years but the result is just zero. I am getting frequent migraine attack due to this problem. What should I do?
