But I don't agree with the "why did she go on the show" viewpoint. She doesn't seem to be holding anyone else to this same standard that she holds herself. She's simply saying, "I'm going to have a hard time believing you truly love me if you had sex with 1 or 2 other women 6 days prior to proposing to me." It's not that he had sex in the past, it's the proximity to the proposal. How can you honestly tell me that you want to spent the rest of your life with me when you slept with someone else not even a week ago? At least that's how I'm interpreting her words. It's not so much the sex, but the timeline. And I honestly don't think it's unreasonable to go on this show and think you can "win" without the lead banging other people. Nick only slept with Vanessa because he knew it was her. Colton ran after Cassie and ditched the other two. So it's not like it's unheard of for the winner to be obvious to the lead early on and they approach fantasy suites differently.
And by the time you get to the top 3, they all think they're the winner. So if I put myself in her shoes, I think she's saying, "I know it's going to be us in the end. So I think you need to know that I'll have a hard time accepting a proposal if you sleep with the other girls while already knowing it's me in the end." Because I do think there's a big difference if the top 3 are "tied" and you need to explore the sexual chemistry to sway your decision, but if he already knew it was Madison but slept with the others anyway because he could, I don't think that's cool.
