Excellent update, the secret is going to be revealed, this update has given an impression that all three I.e. Meena, Ravi, and Lakshmi have been collided and the affair is not new, right from the marriage it seems they have an affair with the knowledge of meena and they wanted to make it public get rid of Murugan and a question is they wanted to get rid of son or not, or whether the son is of Murugan or Ravi, if he is the son of Ravi why he wanted to spoil ths son

Absolutely not, Lakshmi is being trapped here not Murugan or her son. 

The whole plan is to get Lakshmi for Ravi and make her his second wife. I think Ravi might have forced Meena to agree else he will not make her pregnant, him wantedly pulling out at right time and on her stomach proves that this is a habit between them and only explanation is that Meena want to get pregnant desperately and Ravi can make her pregnant but he is not doing it on purpose and might have made a condition with his wife that he wants Lakshmi because he is smitten by Lakshmi's beauty long time back and he made all this plan to get her, I wouldn't be surprised if he is the one behind Murugan's business loss and drinking habit from the beginning and in the past.
