How can I begin to tolerate my husband?

I am a 26 year old Indian girl married for about an year and half. I had an arranged marriage and just cannot cope with it. I hate my husband and feel trapped in this marriage. My husband is way too dumb. I always felt he was but was never sure before the wedding so went ahead and married him anyway. He has failed in his exams and has taken more than the stipulated time to get his graduation. He is much older than me but is worse than me in his job front. He earns as much as me now although considering that he is a postgraduate and older to me he should be in a much better and higher position than I am in. He is embarrassed about his failures in the past but will do nothing to change it now. I just feel he is highly incompetent and incapable of doing anything or getting anything done. I am scared of having a future with him. I am scared he will never succeed in life and will not be able to provide for me in the future. He has absolutely no goals or ambitions and take life too lightly. Do you people think I should leave him or is there any remote chance that he might wake up from slumber and become a good man? The way I see him now, he is a complete loser and failure with nothing but darkness in the future. Would it be wiser for me to just leave this man and concentrate on my career?
