As promised, here's my take on the Liz situation...

I think Nick in particular is very sensitive to people seeing him differently based on his favorable appearance on Bachelor in Paradise, when frankly he was the same person on that show that he was on the previous Bachelorette seasons. Remember, for 2+ years (and still to this day, really) this guy has gotten a LOT of hate. Yes, I know he put himself in a position to receive it, but the fact remains that he's been on the receiving end of enough flak to thicken even the toughest, most confident, most self-assured person's skin. Therefore, he doesn't have a ton of patience for people who suddenly treat him differently after he's gone from being that guy you made fun of for appearing on 3 seasons to suddenly The Bachelor himself and thus more famous, respectable, and/or "higher rung" in the Bachelor world. There have been folks in Bachelor nation who might not have cared one way or another to be his friend, but whom overnight became interested. In this regard, I can totally see his lack of sympathy for someone like Liz. After all, for the better part of a year she was only one degree of separation away from being able to contact him. And she got to know him outside of all this (for the most part, anyway). One night might not be a long time but it's long enough to decide whether you like a person and want to see him again. She got to know him personally, human to human, and should have been able to make her own judgment as to whether or not he was someone she'd want to date. She shouldn't have needed to wait for his flattering spin on BIP or his crowning as Bachelor to find him dateable.

Also, knowing Nick, I can see him have ZERO patience for a girl testing him right off the bat like Liz did with her limo entrance. She would have been FAR better off just coming out and laying it all out there. We know by now that some of Nick's favorite traits in a romantic interest are honesty and transparency; by keeping her cards to herself—needlessly—she killed any possibility here before she even set foot in that mansion.

I've heard people say that Nick shouldn't be one to talk since his existing relationship with Kaitlyn was one of the reasons he waltzed (late) onto that show. The difference is he was already an alum; he would have been allowed on Kaitlyn's season whether or not they had ever spoken, and especially since he was formerly a villain. Secondly, the amount of time Nick had to get to know Kaitlyn could never amount to 9 months' worth (more like a few weeks' worth) and he didn't have much time to pursue her before she was crowned Bachelorette. Also, Kaitlyn becoming Bachelorette didn't represent some change in his or the audience's perception of her. (Aka, she didn't go from hated to loved the way he has.) So, again, I do think Nick is ultra-sensitive to that change in perception and has very little tolerance for the folks whose behavior towards him changed on a dime. And whether or not Liz is actually one of those people, she automatically falls into that category in his eyes because, before he became popular on BIP, she had both the time and access to let him know she was interested.

And let's reverse the gender roles here for a moment. Let's say Nick was Tanner's Best Man and Liz was a two-time Bachelor alum mostly known for being despised and a villain. If Liz had wanted to get Nick's phone number after a drunken one night stand and Nick had said no, he would be a raging asshole. I don't personally think this whole thing stems from Nick being wounded by her refusing him (I personally think if he was truly intrigued by Liz he might have still tried to reached out to her himself) but it does highlight the double standard. Society says Liz saying no is just her being not interested, not ready, or a strong woman who can have sex like a man. Yet, Nick saying no would be just massively dirtbag-ish.

But here's the crux: I personally think Liz wanted to be pursued, and actively. She may very well have liked Nick a lot but didn't want to be that clingy one night stand girl who thinks a fun night means something more than it does. And in wanting to not seem like that girl, she went in the opposite direction and shut him down—a defense mechanism of sorts to protect herself from getting shut down down the road. I sadly get the feeling that this stems from a deeper insecurity on her part, like the assumption that a man she has a one night stand with would only ask for her number to be nice, and those guys need to be weeded out from the ones who genuinely want to see her again. In my humble opinion, the following clip sums this up painfully well...
