is it the right thing to do ?

We were a family of 6 peoples until my mother passed away suddenly .

Here is the context

My mother was a traditional , loving mother. She sacrificed alot for her children . She educated us all, raised us all and fullfilled all our needs . She did her best for us . My mother was a govt school teacher . Its been 2 years since she left us .

While

My father works in Forces . His age is 55 My father was abusive in the start . He was and still an irresponsible father/husband. He is selfish . He used to mentally torture my mother like bachun ka khial na krna , ghr ki traf attention na dena , bus duty se wapis aana , rest krna or gaaon chala jaana . He belongs to the village and still he cares alot for his animal farm and well being of his parents who used to give lesson to him . Still I beleive he is more interested in his village affairs then us (siblings). We still belive mama ki death ki waja zaroor papa ki farmaishain or irresponsible behaviour hai . In her last days Papa mama se achi trah baat nhi krtey they . He used to give her depression . He is still more interested in his village . My Father still has 8 years of service left .

My parents worked hard , gave us education , built a house and provided us the best .

We are 4 Siblings Sister (aged:27) : Masters , Married (2 year old daughter) and she is preparing for CSS . She switches between her home and mother’s home .

Myself(aged:25) : in UK and gonna settle here .

Brother(aged:22) : lives in home and preparing for govt job .

younger brother(aged:16) : Lives at home , goes to College .

We have a maid at home from last 8 years .

Here is the main problem

Papa is asking for 2nd marriage now . He says “mujha duty pr jaana hota hai , meri zarooriat hein , chota bhai ki zarooriat hain , kab tak hum khud dekhain ga , Baji kabhi hoti hein , kabhi nhi hoti , Bohat saari essi jaghein bhi hoti hein jahan oorat ka sath jaana hota hai , “

You can imagine the needs of a Father and a college going child and imagine a home without mother .

POV: Mujha acha nhi lag raha , Like Mama kia sochein gi , are we gonna hurt her ? log bhi batein krain gey . We (siblings) are raised well and we respect our father and want him to be happy and well taken care of .

Is it right thing to do 2nd marriage now ?
