Whats the use?

I read that every1 wants Raman to fight for his love n not to give Ishita divorce staright away. Well, is there ny use? 'Cause Ishita will surely do whatever she thinks right. From previous month, Ishita's verbal n practical bihaviar is so irritating.
Her mahanta n all is killing everything. Apart from Mani, Accident n Adi track Raman has always believed Ishita but Ishita had done the exact oppsite, Raman even called her devi n took care of her feet that she broke in her obsession, he even touched her feet to use medicine. But Ishita on the other hand has behaved like a jerk - blameing Raman for everything, telling him " I hate u" n cheater, liar, in front of everyone then over trusting Sujata n letting him insult Raman, asking him to wear bangles n all. Then she thinks all can be cured by mentioning him as superman through HIS daughter, Ishita got jealous that Ruhi spent time with Raman.
So, my point is, whats the use of Raman to fight for his love when she herself doesn't consider him trustworthy? He sould let her be with Subbu n when she will understand his plan to separate them then she might, just might behave sanely, like the Ishita she is sopposed to be.
Raman is really ill-fated, first a Gold-digger then a regular over-obsessive disorder... ...alas
