How can I get out of this situation?

I don't know much English, I translate from an interpreter. I am not a European citizen but I live in Europe. I came through family reunification and I have to stay married for 5 years to get citizenship. I came with very beautiful dreams, her family said so and I thought it was real. My wife is a few years older than me and he doesn't want me to socialize. I have difficulty finding a job here because I don't know the language. My wife works but she gives me housework. I told her I wanted to go back to my country and she literally went crazy. Why is she acting like this? She doesn't want me to leave the house and she doesn't want me to go back to my country. So I go to a job interview without telling her. Why is this woman acting like this? How would she feel if I escaped to my country without telling her?
