My husband asking divorce for silly reasions

Mine is love marriage but accepted by both side families. We r having 6 years old SON. After 5 months of marriage my husband started blaming silly things ...not cooking well not doing house hold things well even if I do those things properly . He did not believe me after showing proof also . He does not like discussions...resolving issues. He did not show initiation for family life ... whenever I ask why you r doing like this he blames me for that also.i patiently waited ... once said give me divorce Out of frustration. Then he started asking me for divorce. I think he has some psychological disorder. That's the reasion he was unable to understand and think . Believe things in practical and really like other normal people do. He used medicines for that.we took my money and not returning back .now he is saying he will not give mo ey for my son n myself. Can I prove his psychological disorder in court ? If yes can I get benefit from that ?
