Relationships may start with love, but only trust can sustain it. Trust takes over love in no time. For many love comes only second to trust. I can imagine how hurt A is going to be. At this stage after overcoming hurdles together, tying the nuptial knot and sharing intimacy, this is not expected from K. The secret DNA testing is a huge step and a very sensitive private issue. No honest loving husband can tolerate there. Here K is innocent though. Her insecurities don't allow her to question her husband directly and she takes the detour path. Too many events happening too soon in their newfound love, the difference in their backgrounds, her previous heartbreaks, fear of loss and herself being at the giving end all affect her relationship with A. A needs to understand her insecurities, pamper her and boost her confidence.
