Aslem walkuim ​​​​​ I married a girl about 3 years ago the marriage lasted for about a year then we had a lot of arguments so we separated (we never got divorced we both went our separate ways) after 2 years off no communication me and her started back talking! My question is are we still married as far as deen? If not what are the requirements for us to get back together?
