I am a 35yr old man. I got married to a woman of my age. Before marriage, she seemed to be fairly normal but now after spending a month with her I got to understand that she has a very poor memory and very less IQ. She does not understand basic addition, subtraction and simple calculations in maths, neither does she know how and what to speak in front of outsiders. Since it was an arranged marriage we could meet only 3-4 times before marriage that too both us being from different cities our courtship period was very less. I got her checked with a psychologist who came to the conclusion that she has score of IQ which is just borderline between poor and mental retardation. I do not wish to continue with her anymore as I neither have the time, money or the energy to go for a prolonged psychological treatment over a period of 1.5-2yrs to see any improvement. That too the psychologist is not guaranteeing me anything, it is an effort which can be tried and chances are she may or may not improve. It is nothing more than a chance. Her parents passed her off as a BA graduate though in front of the psychologist she admitted that she had not even cleared her class X. I feel cheated big time but am not sure if I file a case for divorce will legal options be favourable to me at this point. Since she is not mentally retarded she has the ability to lie and manipulate things to suit herself and hence my query is under what grounds will I be able to get a divorce from her? Please treat this as urgent as I am a completely shattered person at this point in time.
