I think he is so afraid of hurting Minnie or letting her experience any trauma, especially after the hospital incident and her outburst before that, that he will be trapped in this vicious cycle. I think only Minnie herself can release him from it when she realizes what is happening to him.
Of course it's for Minni he is silent but it does not mean he will act like this that he is not hurt... If he really loves the mother daughter duo he have to voice out his feelings to babita... Then only it will be a healthy relationship... Otherwise again it will be the same situation like for what Minni was afraid....
Hope they don't lead to that extent....
