well i get what u mean to say.. but i will copy paste what i said to 2 of my friends while we were discussing this in FB..For me what Paro did made total sense. She is like a 2 year old left in the middle of a strange road! She doesn' t know how to separate left from right and thus she went to the only familiar place she knew other than her home. PLUS there were 2 more reasons. She was broke other than for the pocket change Rudra gave her and she is not educated to know she can survive somehow. Again the 2 year old left in the middle of nowhere situation. She will soon know better to fend for herself, but not yet.
But above all else i think she wanted to prove a point to Rudra. She was heart sick and broken after hearing what he did. That he never intended for her to go home and it broke her all over again. AND it made her furious too at him for playing with her, so she went back to prove a point too. That there was no way in hell that he will get to use her to hurt her loved ones.
Finally - the man threatened that if she killed herself he will kill all the people she loved, and what was to tell that the same wouldn't have been implemented by him had she disappeared. He might not have of course, BUT would she be willing to take that risk? I don't think so, that she would have risked her mamisa.
But her returning to him meant she will know before he hurt her loved ones..n better yet he would turn to her, to hurt her rather than hurt them.
So in all Paro being who she is, it made total sense for her to go.
