How much Anuj changed since his marriage with Anupama

Anuj was introduced as a sharp, no nonsense fella who never used to bow down to whims of these people.he helped anupama but he did called out her hyprocisy for not  taking CA as her first priority.ALL HE DID TO MAKE ANUPAMA HAPPY.... Anuj did for the sake of love until he broke and left her . 

And now he serving those who abused gk kaka , malti devi and especially mukku .

He has become puppy thats it

                            HERO                to             

Did he really change ?? I seriously wonder. Yes, he could see through people but then what? Why was he not able to see through Anupama? Back then she was fighting with Vanraj and Baa for her rights, but even then there was an insane attachment not just with the house, but even with Baa who character assassinated her multiple times in the worst ways possible ways. Yet she would always go back to her. Touch her feet right the next day after leaving the house when Baa even publically declares that she has nothing to do with her. Was Anuj not seeing all this? Despite suggesting multiple times to draw a line between Shahs and herself, she paid no heed to him. I am not saying Anuj should have just left her and run away, but if he was really smart and intelligent, he should have seen where her priorities lie and she just has too much on her platter to be able to do justice to any new relationship. He could have just remained a friend to her, if being nearby her was so important to him. That would have kept him near her as well and his own life would have been less messy. 

As far as having a child is concerned he could have easily adopted a boy child. That didn't require Anupama to become his wife or he could have started an Orphanage for children and started living there if he is so fond of being in between kids.  Ah ! The mungerilal ke sapne I am getting thinking all the possible scenarios where their lives could have been way less messy had they not married each other. Anuj would have lived his life happily, occasionally looking at Anupama in his office, like a college boy, not getting too attached, yet enjoying her ethereal beauty and at the same time taking care of business living his life in his kingdom, possibly with his kid and his family (GK Kaka and Mukku ) ... Anupama would also have continued her life being more relaxed sometimes serving Shahs with her great food, sometimes serving them with her bhashans, yet never leaving them and getting a kick in life through their taunts and insults. Also being regular to her office defying Baa and Vanraj daily, giving the message of women empowerment, not being in dilemaa about any Choti or Chota ...  

he has transformed from tiger to dogy
