noooooooooooooo riddhima is not a frivolous girl. look, girls really have to be sure about their life partner, and if shes not sure then there will be problems for them later on.
saying that riddhima said I love you for time-pass is wrong. she meant every word. but she needs time, as would any other girl. shes been through a lot too. you cant say that armaan is not at fault at all. hes shown a lot of immaturity in the past few weeks.
riddhima does love him. and he loves her back. all the moments that they shared together were special to both of them. but lets remember that these people are HUMAN. they have faults. they are layered like onions (hopefully, they dont smell that bad). and we all need to realize that love is a two-way street.
both of them need to mature before they get serious about one another. the way they are now, is disastrous! give them time, they'll come around.
