I personally have never been in a relationship and have never experienced anything. However I have learned a thing or two from my friends and their relationship experiences. First of all, I don't think it's fair to say that cheating is just in a man's nature because as some of you guys pointed out, women do it too. And women cheat more then men when it comes to wanting their pleasures fulfilled; yet women are seen to be negative when they do that, whereas a man is not seen to be negative, just fulfilling his desires. I think that's just a bunch of bull. If my boyfriend or husband ever cheated on me just ONCE even, I would NEVER forgive him. If he cheated on me behind my back and I never found out and we made love several times over the course of that cheating, and I found out about it later, I would feel that someone else invaded my body. It wouldn't feel right then. Nikki must have a STRONG heart to be able to forgive and I guess it really does depend on circumstances, but I for one, would never ever forgive a man for cheating on me. If I'm pregnant or on my menses and can't do it with him for a while because I can't or don't want to, he needs to learn to control himself too. We have urges we control when we can't do it with them so they have to be fair to us too. Seriously, men and women both need to understand and love each other and not give into temptations from the outside world, but it seems like people don't mind and feel that they can do whatever they want. Our society's just messed up. Abhi did do something once and he did repent...so maybe it was okay for Simran to forgive him but I wouldn't marry him again like she did. The character must have loved him wayy too much to forgive and let bygones be bygones. As you can see in the show, everything is blamed on Kiren anyways for seducing Abhi in the first place. But what about Abhi? He cheated on her too and because he had his urges...he didn't think about Simran at the time. Kiran is a ----- but Abhi didn't need to fall for her charms and beauty.
So yeah, in a nutshell, no I wouldn't ever forgive a guy for being unfaithful towards me. I'll throw it at him everytime he says or does something until he's in his grave. Then I'll let God deal with him then.
