After he got married
My brother and i used to be very close. He is 13 years older than me . After he got married and have children, he changed a lot, like very much. Nowadays, everything my sisters and i did seems wrong in his eyes.He becomes sort of judge mental.And all he cares are his wife n in laws . He treats his sisters in law much better than us . My parents noticed it too but i dont know, maybe the fact that he is a doctor (my parents were the one that asked him to be) ,cover all of his behaviors.
