Yes, Ofcourse I believe Radhika.
Knowing mishti I also know she won't take this huge step if she wasn't sure, especially when she is shown family oriented.
As of mishti giving veer a Chance? What? Pehle engagement karke dekh lu, nahi jama toh break up kar lungi?
That's not the mishti I saw. She totally loves Veer n accepted him the way he is, with his flaws.
Ab agar ppl are adamant of breakup toh literally kuch bhi faults dhoondh sakte hai.
Makers knew ruhaan angle hona hai toh atleast earlier mishti ke monologue de dete abt being unsure or being jittery abt engagement n wedding. But they showed nothing from mishti side that she is unhappy with veer.
