Off course he would feel very guilty for as he never wanted their consummation to be like this way. Both were angry and turn into a sex. Both got carried away.
He was feeling guilty but she still should not have left his room.
I don't know what I'm going to say may make sense. But this is my POV.
Meerab came for murtasim when mb came to her. But here she saw murtasim with haya in a intimate position. She was already heart broken becoz he left her and he never heard what she wanted to say and again again blame her with rohail issue. So she gets pissed. And after fight murtasim forced her, they both fought but in that scenario she gave in becoz deep in her heart she loves him and both meerasim are possessive for eo. So both showed haq on eo.
After all the act they both realise omg what we have done. So meerab go back to her ego era. She never accepted her mrg, nor him as hus, nor his love and specially her love for him. So how will she accept the fact that she did it with him. How will she face him. If she accept these things then she have to live in the "cage" that what she refers as this mrg. So she left. They didn't need to bring up the contract here in the voiceover they should have simply say how can I do this? Till now I never accepted him as my hus and now I did it with him. So going forward I have to surrender to him. And I won't do it. I will go away from him becoz he makes me weak emotionally.
Meerab is stubborn, she won't fall infront of anyone, and specially murtasim. After this definitely not.
