Your wife is a very emotional and a sentimental human being.
She seeks attention, and if its not working according to her liking, she either gets into a depressive state or burst out her emotions in the most uncontrollable ways.
It has been since her last birthday that the problems in your domestic life has aggravated. But it will become better with the start of the new year.
Now the only solution i see here is , handle with care.
As she cannot take rejections , its best if you increase your love quotient, a bit more pampering and a bit more agreeing to her in daily matters.
