I think she needs to exhaust all her options before thinking of divorce.
1st, why didnt her parents make sure studying wouldnt be a problem?
2nd, it seems as if the MIL knew her plans to study because she made a snide comment about it. If thats the case, they’re switching the script on her now. Which isnt fair to her.
3rd, she needs to talk to her husband right away. Be tactful about it, dont get upset or irrational. Discuss it and let him know she has so many dreams and hopes for the future and now she sees them going up in flames as she makes achar gosht for her MIL (btw achar gosht rocks).
4th, speak to her own parents about this. She needs to have a strong support system backing her up. Ask her own parents what they think about this, has her MIL said anything to them about it? What do they say about all of this?
She cant just go and file a divorce willy nilly, try and see what she can do to remedy the situation first. Who knows? Her husband might say “you’re right”.
IF nothing works, then she might want to go that route because its not fair for a woman to alter her entire being, dreams, career, personality, lifestyle, etc just to be married. Thats torture on the soul and just builds resentment within a relationship.
