After nikah one should try to live peacefully with spouse. Sometimes a man or woman has some shortcoming but his/her other habits are so good that it overcomes the shortcomings; for example the said woman has the problem in hearing and listening but it is possible that her other characteristics are so good that they overcome her shortcomings i.e. her morals are so nice or she obeys her husband etc. In contrary to it, sometimes a woman does not have any visible shortcoming but her morals are not good and she does not obey her husband. Then the first type of woman is better than the second one. Hence you should not see her outer things rather keep in mind her other characteristics. Do not give talaq immediately. Talaq is most undesirable thing among the lawful things before Allah. However, in future if there is no way of maintaining the relation with her then submit your query again and know the ruling.
Allah knows Best!
