What's wrong if gopi marries dr Krishna

Why this hypocracy in our india if dharam who is 50 plus age and having married son can marry young girl meera then gopi who is 40 age cannot marry why? Gopi daughter's are so selfish they r not even carering about their mother and Dadi and whole modi family are treating gopi and kokila as a big bruden to the family then if dr krishna want to marry gopi and even want to take kokila with them then what is wrong in it, gopi should move on from past and our indian serials should change in our indian serials they will show good bahu but forget to show good daughter like gopi is a good bahu but she is not a good daughter similarly meera and vidhya not even taking care of gopi our director's should show good daughter along with good daughter in law cuz girl parent's r also parent's we should not neglect them like boy parents girl parent's also needed love and care
