Why? Is this part of Islam? Of course not, it's cultural.
Many women don't like it, yet they agree with it.
On top of that, why do guys do this? I would rather be married and live in a hostel than to be married and bring my wife to live in the same house/flat that my parents and sibling live in. Why don't men just rent an apartment.
The first few years of the marriage must be the most exciting, right? But how can it if you live with the in laws? If the couple want to kiss in the living room or give each other a romantic cuddle, they can't if someone else is in the room. That's just one tiny example. I'm sure I don't need to further and give other obvious examples.
Does anyone find the whole "living with the in laws" thing just plain weird and bizarre.
