well first of all this is ekta's show so two lovers cant really get married in first go. they have to get married to someone else who is bad or too nice then have an extramarital affair with each other and make the situation so bad that they have no choice but to be with each other again.
secondly according to the show D family is the most loving and caring family yet i have never seen such a dysfunctional family coz the young generation can never really speak their heart out. classic example is ovi-arjun- purvi triangle. situations over there got worse coz of the lack of communication and misunderstandings and ofcourse assumptions. here too if sachin and gauri gets married, i am pretty sure nobody is going to bother to ask gauri if she really wants it or is she in love with someone else. i am not saying gauri is in love wid soham but she def has strong feelings for him and that is quite visible in the way she is with soham. she cares for him unlike sachin with whom she has not connection whatsoever.
so is archana blind to soham gauri connection?
