I am a gauhar fan and i strongly believe that she was right in season 7 she stood up for herself and she was right andy displayed her personal stuff on national television though it was not telecasted he did in front of other men who were present in the house and for god sake that behavior needed to raised and opposed and the problem was andy did not accept his mistake immediately
on the other side tanna is making a mountain out of a molehill yes she was abused verbally and its not acceptable but when someone is appologising and touching your feet and is ready to face any consequences for his action which he knows is wrong its quite wrong that you are not ready to give him a second chance
gauhar was abused by armaan she kept minnimum interaction with him and she even started talking to andy although after some time because what he did was WRONG AND BIG ENOUGH FOR ISOLATING HIM
