Even if she thought it - iske bas ka hain nahi. Sha has control over his temper and can see the scene or angle (or season) through. This one can’t. And in her current jal bin machli state, she’s cutting off her nose to spite her face even further. Very stupid.
Sha ko zyada kuch karne ki zarurat hi kaha hoti hai? Ye sara time zeher ugalti rehti hai.. Just like Prenka used to do with Ankit.. but in her case, they showed their good times too (somewhat)..them supporting each other too. when Shiv and company attacked.. But Tina? I have never seen her once take stand for Sha..not once. Infact she has always picked random people over him.. She is solely responsible for this narrative going against her..
