Problems with in-laws

Q: I require some advice regarding a situation with my in laws. We don't have the best of relationships and my mother in told me that I have never done anything to be a daughter to her or a sister to my sister in law. After this, I was hurt and decided to keep away from them. Yesterday my father in law approached us and my mother in law lied saying she never said that and lied and said I told her I suffered in their home. My father in-law believes her. My mother in-law then called me a ... and told my husband she wants nothing to do with us. My father in-law phoned me today, shouting and insulting me and demanding I phone my mother in-law and ask her for maaf. He said she is my mother in-law and I must do it. And then he told me who am I and said you are nothing and he cut the call. I require advice on how does one handle this situation and would like to know what are the rights of a daughter in law.

Saying "Me tumhain talaq deta hu"

Q: While we were fighting on some issue I said to my wife that Me tumhain talaq deta hu 2 times. One time clearly and the 2nd time she kept her hand on my mouth so words were not delivered clearly. That time I was in anger. After that I felt that I have done a big mistake. We love each other and never thought to leave each other. Please guide us what is the state of our relation?
