I highly doubt that ML is so oblivious and insensitive that he wouldn't notice his ex-sister-in-law's actuations towards him. I'm sure he did , but his mistakenly tolerated her. What he didn't know was that bitch had already told the FL her intention to take him away from FL and bear his children . The mistake of the FL was, she didn't tell her husband. So her suspicions and insecurities grew and grew until it became intolerable to her.
