I am working as a software Engineer got married with a girl, after two months i came to know that the girl is suffering from thyriod. Now we suspected and we go for complete health checkup for her. there we came to know with those reports, that she has a thyriod problem. I didnt notice this at the time of marriage.She and Her parents know that and hided from me before marriage. i didnt expect a wife like that, I totally upset about this and i cant able to accept her in my mind. Now they are telling lies that they too dont know before marriage.I have phone conversation as proof. in this phone conversation her mother told to take t3(thyriod) related tablets regularly.Is this enough for evidence to prove? Is there is any provision to void this marriage? Please help me..
