Whos at Fault for d LOVEBIRDS split?

Why is that these love birds are falling apart, is it that Mahek's unnecessary doubts are taking them apart, is it Varun's unnecessary friendship wid shivangi or is it the devil Rishi who made way for all these problems or its the circumstances which is making it impossible for them?

non eof the above!!!! charu and swayam!!!!!!!!!!!!!!!!!!! but mostly jharu 😡

definitely varun's fault
he wuz being such a jerk when mahek wanted to see her sister, he had no rite to make her choose between his family and her sister 🤢 , mahek never told varun to stop talkin to sujal cuz her sister had problems with him,, he also never even tried to explain his relationship with shivangi, plus before this ever happened he wuz angry with mahek after their marraige because he thought she liked rishi[and wuz unhappy about rishi being around all of the time since he wuz also the father of roshan]. mahek always had to explain herself and now that its his turn he doesnt even bother and accuses her of not trusting him
mahek wuz also a little responsible for their split cuz she actually believed wut rishi said after all that happened before 😡
