Ok DA I dont know the full story, but tell me honestly .. this was a love marriage, you wanted to marry this guy? What kinda love was this? cyber love? where did u find him? Did u fight ur family to marry this dude or something? Didnt ur family investigate well before accepting? yahan kya ho raha hai?
Secondly, you mentioned you MIL says tumhe koi kaam nahin aata and beforeon she was very interested in your studies. U are an engineer MA. But tell me honestly, tumhe ghar ke kaam aate hain? Are you good at it? Do you give it your honest shot? Because a person complaining abt ironing clothes doesnt seem to be familiar with housework much.. so explain to me, do you know any housework or did u spend all your time in ur engineering books assuming your inlaws would make u sit on a throne? 
Because if you really thought so, you are a big fool.
You mentioned your MIL used to be interested in ur education and now she doesnt mention it. why should she, whats the purpose of mentioning it? Before she was interested because she wanted to show “log” ke unki bahu to mashallah se engineer hai, now she the logs wont come and do the housework, and nor will her praising your engineering do it. I think you need to leard hard facts, inlaws mostly are only interested in the girls education prior to the wedding and after if you bring big cash (not all, but some inlaws that is). After marriage most inlaws are only interested in how good u are in mingling in and doing housework. Your inlaws seem to be the kind. I think its sad that you didnt realize this in 6 yrs, yeh sab kuch to insaan ko kuch dino mein hi pata chal jaata hai.
