Does this come under DESERTION

when the marriage itself a question as the girl was not in sound mind  during wedding let alone the question of desertion...in fact you sent her out of your home, so it can't be desertion...just request the court to void/null your marriage as the girl got mental problem before/after  marriage

 anjali has given a correct opinion

If the husband has made efforts to bring back the wife during the 2 years period of separation and the wife has refused to co-habit .... then u can claim it is desertion ...... U claim your wife suffers from mental disorder problems .... if this is true you can file application for nullity of marriage in the famlly court .... But it wll be necessary to prove her mental disorder condition
