I think IQ purposely avoids questions on Neha and I genuinely feel that he does so to protect his and Sneha's relationship from any controversy and to avoid media from making mountains out of nothing.
As far as Neha is concerned, she had called IQ " WEIRD, FUNNY, HILARIOUS AND A PAL" in her interview (short takes).So, I don't think they have any problems getting along.
My take is that IQ plays safe by not talking about his lead co-star.In any case, I don't think IQ is the type to be rude or repulsive towards anyone.
