Haan yaar, just If Jalal came back and informed Jodha that Ruk was pregnant and he was going to meet her, she would have joined him and been happy for him. Jodha was not sad that Ruk got pregnant before her or anything, she was sad that Jalal left her just like that, when he told her that he will always be by her side! Jodha would have been ecstatic that Jalal's wish of becoming a father would be fulfilled.
right ela... now i wish Jo distances herself from him till he gets one more shock of his life abt Ruku's lies
