1.You should feel lucky enough that in the given circumstances there is still a positive sign in your life,that you are loved by your husband inspite of evil tactics adopted by your MIL towards you.
2.From time immemorial a few Mothers-In-Law have developed this type of attitude of harassing Daughters-in-law under the false impression that the DIL has taken over the control of their son from them. They forget that the son before marriage was doing his duty towards his parents & siblings only and now after marriage he is doing his duty towards his wife in addition to the duties he was doing earlier towards his family. Such Mothers-In-law forget that each such duty is clearly demarcated in the sense he should be a good son to his parents, good brother to his siblings and good husband to his wife. MIL thinks all these years she was looking after her son from an infant to the present stage and suddenly a stranger in the name of DIL has taken control over her son's life.
3. Start praising your MIL for very small things and win over her thereby she might develop soft corner towards you in future.
4. Better to move to a separate residence with your husband, preferably nearer to your work place and convince your MIL & husband citing the need to work.
5. Time is the best healer and as the day passes such things fade away and in the long run when you look back at your life, you will wonder how you overcame such hurdles. So be patient.
6. Do not, at this stage, think of divorce and lead a happy married life with your husband.
