Also, even the wife of a king did not have freedom to approach her husband unless he give her permission. I'm sure Bathsheba was overwhelmed with fear when she was brought to King David. And in fact, when David had her husband Uriah killed on the battlefront, II Sam 11:26 reads: "And when the wife of Uriah heard that Uriah her husband was dead, she mourned for her husband."
Uriah was very devoted to the king. He refused to sleep in the comfort of his own home. He slept with the servants on the ground by the king's door. He felt that if other servants of the king were in tents and in fields, he should not have any luxuries either. Even after David got him drunk, Uriah still refused to go home and slept instead on the ground.
Uriah had an honorable heart and I'm sure he was a devoted husband, too. Bathsheba must have loved him dearly.
