Nanhi took decision for Mohan's sake

I read so many posts about Nanhi's decision to marry Beera against MM's wish. But I think she deliberately did that.

You know she knows one thing, if any thing goes wrong with any member of Mohan's family, be it Nanhi or Megha or Addu or RJ, Mohan gets hurt badly. Nanhi never wanted that Mohan should get hurt. So, acc to me, she knows Mohan is right, Beera betrayed her. But forcing Beera to complete all the rituals, she somewhat pacified Mohan. She tried to convince Mohan that he was not wrong in saying yes to Nanhi-Beera's marriage. Otherwise, Mohan would have taken the whole blame on himself and would have gone into his shell once again like he did in Addu's case.

She will not accept Beera as husband, but wont show it to any of the family members. It was Nanhi, who forced Mohan-Megha to accept Beera. Now she wants to take the blame on herself for that.

Mohan trusts Nanhi and although, with heavy heart, will accept their marriage and hope for the best.

Mohan will be relieved, although a little bit after that. That is Nanhi's mission right now and she has succeeded in that to some extent.

What do you think guys? Am I right or not?

This would be an extraordinary, not run of the mill twist which would be quite interesting if the CVs thought about it. It may lessen some of the negativity from yesterday's episode (though I still am not sure what the issue was...)
