Ohh if i was Tejo, i probably wouldn't have gotten married to Fateh in the first place but nevertheless lets assume, what i would have done when i find out fateh has cheated on me.
First thing i would file for a divorce and go back home. i wouldn't keep an eye on the Virk house if Fateh goes to jail- after him using tejo, accusing her of infidelity and lying to his best friend, bro idc, who is he even?
Then after getting a divorce i would shift to a whole different city/country so that Papa Sandhu and fam don't come behind my back for another marriage, also so i don't have to look at Jasmine or Fateh's face again.
Tbh i would be more angry on Jasmine than Fateh because from my pov i feel Jasmine was family before Fateh, she was supposed to be loyal after everything Tejo had done for her, Fateh was also bad but not equally bad so if he redeems himself i would accept him back as a person in my life but niether as a life partner nor as a friend because i'll never be able to trust him again.
but jasmine i don't think i'll ever be able to accept her back after everything she did, even if she redeems herself.
