I have been married for a year and a month now, we are always fighting I don’t
really feel happy in the marriage anymore I have asked him several times to go see a counselor with me but he refused, I have also asked for us to see a pastor which he also refused. At this point am really contemplating leaving the marriage after having my baby but I want to go with my child. He has agreed to give me the divorce but says I won’t leave with his child. I would have involved his mum or sisters bu they practically worship him and can’t tell him when he’s wrong because he’s an only son. He also told me dt no one can talk to him or make him change his ways not even my parents or his. Am really confused don’t know what to do until I contact Dr. Agbadado through email: [email protected] everything change and all my problem was solve within 24hours also call him +2349073244122
