The actress took to Twitter and complained about how harshly her character had been judged for cheating on Dev (Jimmi Harkishin) with Stella Price's (Michelle Collins) partner Karl Munro (John Michie).
"Use of the word "slag" for a woman who is "cheating"commonplace with you tweeters and nothing is said about the man WOW #justsayin #baffled," she wrote.
"Since doing this story about sunita and being back on twitter I realise that we are still in a world of misogynists #2012...yawn yawn yawn bored of the misogyny now!"
When a follower pointed out that the backlash could be because Sunita's affair painted her as a hypocrite, Gulati replied: "Change is as good as a rest...maybe but most people are [hypocrites] when u scratch the surface great debate.... That's the beauty of drama !"
Gulati recently said that she believes Sunita is genuinely in love with Karl.
In a new interview, Harkishin suggested that Dev has been "honourable" as his relationship deteriorates.
