Almost all of us are in Swayam's side, when it comes to the reason of the breakup. We all were angry at Sharon for what she did, and none of us wanted Swayam to forgive her easily. Also, we wanted Sharon to work her everything off so as to get him back.
But what is being shown now, is not a part of Swayam's character. Yes, he has been shown to hide in his shell when hurt. Yes, he has been shown as yelling out, and even being extremely rude and hurtful. This isn't what's being shown now.
Also, he is an extremely consistent person, never impulsive. That is ABSOLUTELY not what is shown now. He is jumping into conclusions and making decisions on the spur of the moment. Nuh-uh. SO not Swayam.
Plus, kuchh bhi ho, Swayam can NEVER NOT LOVE Sharon. It's a given constant, chahe uska manifestation and expression jis tarah se bhi ho.
So..yeah, this isn't Swayam.
