WOW! Is it me or do these women have some power !?!?

In A Thousand Splendid Suns Jalil's wives seem to have power over him. It seems to me that they are the one's who don't want Mariam living with them. It seems like the wives are controlling Jalil to do what they want and think is best. Some things that led me to believe this is because in Chapter seven, when they inform Mariam about the arranged marriage the wives are the ones who are doing all the talking. The father just sits there looking down. He to me seems like he doesn't want this but is going along with it because this is what his wives want. I think his wives bring up the guilt of him cheating on them with Mariam's mother in the past and that this is all his fault.
I started to go back to other parts of the story, which help me believe that maybe his wives are the ones forcing him to do this. So, lets go back to where Mariam was in her father's guest room.

"That night Mariam couldn't sleep for a long time. She lay in bed looking at the sky, listening to the footsteps below, the voices muffled by walls and the sheets of rain punishing the window. When she did doze off, she was startled awake by shouting. Voices downstairs, sharp and angry. Mariam couldn't make out the words. Someone slammed the door." (p.39-40)

Hmmm... I wonder what they were arguing about? This was probably her father arguing with the wives to get rid of Mariam. The wives wanted to get rid of her but he probably objected to the idea at first because this is his daughter they are trying to get rid of. I don't think that Jalil did not care about Mariam. I think he cared about her deeply, the problem was his wives were in the way of him expressing his love towards her. In the past when Jalil would go on his visits to Mariams house to see her every Thursday's, his wives probably sometimes made him not go. If Jalil did not care about her he would not have visited her in the first place. I believe that Jalil is just a weak man, who can not stand up for what he believes in. I mean he needs to become stronger and be A MAN! This is his daughter. His own blood. And now he is letting her go only because his wives don't want to be embaressed by their friends and the people around them.
