I have seen actor playing Jayesh as rich, strict, bitter, annoyed, stubborn father with his daughters in two of his earlier shows,
in both in father role he was loving and possessive, but angry & hurt at same time that his child went against his wish, be it in career or marriage choices..
so his father role cuts links with her, but reconciles later when his daughter is in deep troubles.
Here Jayesh was supposed to be selfish man, smitten by young lady leaving his family of 30 years for her, but feel in writing & execution they went overboard in showing him as if a full vile irresponsible indifferent, heartless father.
Just if we go back & listen to speech Amruta gives about her Baba in anniversary function in first week episodes,
it hints Jayesh was a responsible caring father, he sacrificed few things to give better education & life to both his children before Amu started earning, and was proud of Amu & Harsh boasting his upbringing.. but alas now..

neither she wants Amruta to inform before courts Ishika & EMA as driving forces for Jayesh forcing Bhavani to sign divorce papers with mutual consent on lack of compatibility reasons,
she will also object Amruta informing how Jayesh emotionally manipulated Bhavani to run away from her children to village all alone, in return of a
hope she will also come to know from Ishika on Holi that she is now their 5th floor flat new owner, not Jayesh.
