why "jab bharosa ek bar toot jatha hai.."

what was the need of that dialogue yes'day???...krishna was looking a bit strange that tym...kya uske bharosa bhi toot jayega ???...that pratigya ignoring him or will it be a turning point in his mind to leave the house and make pratigya free from all these problems and only living their lives????...i have no hopes in cv's ...thay will make the stories as they like...but dont want a drift btw them ....its tym to live not in jasoosi and interfering in others lives. ..god bless all...
