Yes! That is the fact. Soon after one falls in love everything is so perfect so nice so rosy-rosy as Sona herself told Dev. Also, till now Dev was a perfect BF, an ideal BF whom every girl wanted including me. But now after marriage the thorns are showing up. Dev is not ready to share his thoughts, his problems with Sonakshi. He himself wants to tackle the problem and Sonakshi is just trying to fit in all the time.
This is all what marriage is all about. We saw Dev behaving badly with Sonakshi because of family but I hope that Dev is able to balance all this and comes out to be an ideal husband too. Till that time - "feeling very bad for Sonakshi" but really thats the story of most marriages.
