A way out

Try to meet the marriage counsellor or even the psychiatrist to assess and bring about changrs. That's why our elders say give 6 to 1 year of time post engagement to assess both the behaviour. I believe you both have to stay together for some more days to figure out the possibilities. My suggestion is to give a last try to this marriage. If it doesn't work you anyway have an option.

Its too early to think about divorce. Why do guys nowadays take solution as divorce of any problem: 1.No divorce possible till completion of one year of marriage as per hindu marriage act. Until & unless by mutual consent 2.You can't judge a person by few months that too in long distance relation. Give it some time 3.Its a question of a girls life. What is the guarentee if you divorce her & get married to some one else- you will be compatible 4.Fear God- Though not written in law but what if after years you get a daughter & her husband think to divorce her on no grounds. All have to pay back here only. Thanks A true feminist

Go alone and consult a psychologist. Not marriage counsellor.  Tell him about your wife's anger and other symptomps and find out whether is it a problem or not and if it is a problem curable or not.  Take one more appointment with him  to visit him along with your wife.   Take your wife to him and tell her that you have problem of  anger management and do not tell to her that actually for her problem you will be visiting him.  This you can pre-arange with the psychologist.  If the psychologist tells it a minor problem and it can be tackled with, then live happily.  I see that in every human beings life there are ups and downs, pleasurable moments and sombre, sad and black days and moods.  One should not quickly jump to the conclusions about evaluating a person,that too a would be life partner.  After psychologist's evolution shows that you will have perennial problems in matrimonial life, then opt for snapping the ties.  For that there is a provision for annulment.  But that can wait.  Go for psychologist first.  Best of luck. 

hardly one month old and you spent with her only two weeks of marriage and no presumptions what to do and what not to do 

because if the steps you take may reflect in your future married life 

as you say that before marriage she was good and only after marriage the behavior has changed may be she is worried about living you and the idea of staying in different place after marriage also changes the behavior 

so if you want to take advice of a psychologist you can but it is very early to take your wife to psychologist which may spoil your relations even more and there will be no option for you.
