I wanted suhana and dev to be together. How can suhana marry Nihal. When Nihal came back he did not wait for suhana, did not say anything to her and got married with Mega. (jaise us se shaadi ke liye bahut jaldi thi)that time Suhana got divorce and was ready to get marry with Nihal.
Now Nihal is married with Mega and they have a kid so she doesnot want to break their married life. Sohan ka bhi kya hoga. and one the other hand Mahek loves Suhana and Dev also loves Suhana. Agar Suhana dev se shaadi nahi karti thi to Mahek to toot jati thi. Mahek ka kya kasoor tha us ne to apni mom to dekha hi nahi tha. Sohan ke paas us ke mom dad to hain.
Koi bhi aurat kisi ka ghar tod kar (married life) kush nahi rah sakti. Nihal doesnt love Mega (why did he get married to Mega)but she is her wife. He can stay with her same like he stayed before. Thats the punishment for Nihal. Shaadi koi khel nahi hai jab chahe kar di aur jab chahe (pehla pyar mil gaya to) divorce le liya. I used to like Nihal but since he got married to Mega I hate him.
Thats the reason suhana didnot marry with Nihal. and she has taken a right decision. She wants Mega and Nihal to be together.
