After today ep her mom will only make things worse. From supporting 1 abuser will support R cause she can read her daughter
couldn't read her pain,needed extrahelp to trust her but reads what's convenient for future. 1 guy with clean image,on top of all rich,can provide 1 easy life for Sharmas and can accept A with sad past. Again will go against her daughter wish and decide for her.
The sad part is R will trust this person and go out of character to win A when the girl is yet to leave back her worst years and first learn to accept herself,how to love him when she can't love herself and be strong for more than few minutes?? Hope the team breaks fast or A finds out and cuts R wings,let everything happen natural not cause someone is desperate to not have 1 daughter single.
Bro-sis angle will also add drama;in this conditions,sorry,but won't blame his mom fully once she sees Sharmas trying to get her 2 boys,not after those 2 overdramatic scenes:parents proposal rejected and BH hall protest. Will have Ira's aunt too to fill her ears with poison that all they want is B fam fortune and that was their plan all along. So if she ends up throwing that fam out if they ever dare to return (and A will suffer only cause she's part of that family) no shock.
She was already unbearable without sharing screenspace with him. If R wants to go ahead and win A love can do it on his own,no partner needed.
Imagine their mom situation if both sons get married in same family and get that madam as mother-in-law. 

let's see for how long cause if their mom will find out what boys do meeting Sharma sisters...
She could use her influence to make sure A won't get 1 job once she's out of HOB and R could help her in secret.
