Couple relationship is built on passion, intimacy , commitment , trust and love .
Usually within first few years passion will fade
Intimacy is like salt in food it should be there
In Devakshi that is missing
Love , trust and commitment are there
Intimacy is important not just physical it should a connection .
If they have these elements in relationship no one can break them apart .
I think Devaskhi missing Passion & intimacy still it is working , but if not intimate marriages will end up in divorce even after 20 or 30 yrs it can happen.
So wait and watch how Devakshi going to find each other through this troubles
