Well Suhaina if you are not married yet, then the ball is in your court, you can ask your hubby if you guys can live separately but nearby. If you already agreed to this condition, it's unfair because he already told you in advance. But you can still mention it...he might be a mellow guy n willing to listen. Just make sure you keep it clear that you have nothing against his parents, it's just that you want to live alone with him. My point is even if your in-laws are perfect angels, even better than your own parents, it is still hard to live with them.
Stuff you can't do living with in-laws:
-cuddling on the couch and watching a movie (nope you have to go to your room and even then they'll be like 'humaray saath gul mil nahi rahi')
-leaving the dishes in the sink and deciding to wash them tomorrow (it seems like you're leaving them for her)
-skip making dinner and just eat mcdonald's drive thru
-walk around in your benyan
-Have your house be a judgment free zone!!
People often say it's about caring for your parents, but honestly, most desi parents i know are relatively young (50s) and pretty independent; they are healthy and sometimes a little distance creates more appreciation and love than too much. Think about if you had to share a room with all your siblings vs. each having separate rooms--there is less conflict when everyone has their own room. My best friend lived with her saas who was her own aunt for 2 years and the saas just started deteriorating after that because she started delegating all her chores to her bahus and then she didn't really have any role left in the house except bossing them around. Something to think about...
