I got married 3 years back . But things are not going well..actually my hubby is not good with my parents . He started making fun of them showing them down in front of others. Always try that I cannot meet with my parents. Life is just like hell...what to do

I think you waited too long to express your disgust with his behaviour towards your parents. I mean for three years you allowed him to make fun of your parents and ill treating him. You should have reissued your voice against it at the very onset. You should not have tolerated his bad behaviour towards your parents from the beginning. Anyway, better late than never. Tell him straightaway that his attitude towards your parents drives you mad and you will not tolerate it anymore. Either he starts behaving well with them or sear all ties with them.
