Short temper, aggressive every time.

She is very talented and very good but i think she is suffering from some mental problems she like,s everything should happen as per her condition if i am doing something without her knowledge situation is like india-pak war. She like to involve in every activity like a superior (mean she knows everything) i have provided everything but she always discourage me ( you are a big dump .. You did not give me happiness ) and she compare always with other successful relatives ... In my case may be you will consider as husband-wife fight but situation is very different. She is the best and she knows everything is my problem ... From childhood she faced so many problems so i think her mental condition is effected from her childhood situation. Please solve my problem
