In life people do a lot of things that they never at the time think may affect other people deeply. I don't think any one of us can say 'I have not'.
In Disha's case she just got a bit carried away and she has offered an explanation - even if it is via chillyflakes old id (that's between chilly & Disha). She really did not mean to hurt anyone and did do a lot in establishing the DK fan base.
So look at her explanation with the same open heart as you did Ashish's.
Ashish is new to this fame game and he will over time develop a protective layer. He has chosen a profession where people will try and take advantage of him. Hopefully, he will still stay the same nice person but maybe not so openly and trustingly.
Neither Ashish nor Disha had anything bad to say about the other and except for a lot of hurt feelings and bruised trust .... all I have to say is .... Time Time ki baat hai
So let's put an END to the whole sorry saga.....
