i think its definitely important to confess because then its actually a real commitment since their relationship is so on and off all the time-- its hard to say if they are together or not anymore since they dont label their relationship as boyfriend girlfriend. after the first date they didnt exactly have others and just causually were affectionate until the problems began so i think armaan doesnt know where he stands with her anymore. he probably feels like he has expressed his feelings by his actions but when ridz does show her feelings, 5 sec later she is regretful so armaan is like confused with her behavior.
BUT i totally think that armaan should just say it because girls dont really like feeling vulnerable in situations like these. armaan sort of put her in that situation by saying she cant have him now because she cant change her mind so now she most definitely is not going to say it first because she doesnt know at all what his reaction will be-- she sort of got herself stuck in a complicated situation...
