Not having sex with wife for 1 year since marraige and when asked she refuse

Asslam o alikum, I have been married with my wife 2 years ago and since our first night we don't have been physical with each other. She asked me after 6 months about sex and as my father was on dilaysis at that time and in bad condition, I said we will do it later and then after my father's death after that year i started asking her about starting of intercourse but at that she told me she needs time. She said she needs two months i waited two months and then when i asked her again she kept refusing untill today i am looking for a job and now I'm in uae and my wife is in our home coutry. My question is have I done wrong in such situation?
