I always thought that they took it one step too far in this scene. Was it really necessary to make Melissa a cheater as well? Isn't it enough that she is this overbearing person who's obviously wrong for Stu? We understand Stu's predicament clearly, so was this just to "seal the deal" so to speak? And I mean for the audience. Stu himself knew about her infidelity and decided to stay with her despite of that. I guess that makes him even more spineless, but it also feels like the filmmakers are hitting us over the head with characterization. It seems like a copout, in my view; Let's make her really bad. "That's not what you do." is a really clever line and reveals tons about Melissa and how she views Stu. That line is the clincher, really. That's what pushes Stu over the edge to finally end the relationship. It would have been nicer if that would have been the focus of this scene. Her view of him and Stu standing up to that, not some affair that happened in the past. It's a fine line to walk between too much and too subtle, and in this case I think they went a bit overboard. Perhaps in this kind of film that has to appeal to a broad market it's better to be safe than sorry and make sure that there are no misunderstandings, i.e. dumb it down so everyone gets it, but still, it would have been nice. Anyone else have any thoughts on this?

Teddy, What if Melissa says something (right before her "You're such an idiot" line) about Stu just now deciding he's going to be upset by the cruise last June? Just to stretch it out a little? I think I know where you're coming from, but, knowing what we know about the Melissa, don't you think she is the type of person that needs a reason other than "sometimes a guy should be able to do what he wants to"? (and that is the best reason when you get down to it) If Stu wants to break up she would just push and push and push until Stu just started blurting things out. The way it's written just makes it much cleaner.

Yeah, but I just think the "cheating" aspect has been done so often in movies. It's an easy way for us to dislike someone but it's kinda lazy. Melissa's flaw of being controlling was enough, in my opinion. And no one is pure evil. A character should be a bit more dimensional than that. Melissa could even have had an arc where Stu breaks up with her and only then does she realize her mistake. That way she would at least have been portrayed a bit more human and not only like a caricature. Plus, it would have made it more credible that Stu liked her in the first place.
