I'll try and give you guys the sparknotes for the scenario here.

Met this chick a couple weekends ago through a friend, we clicked, I brought her home and we go the distance a few times that night/next morning.

I text her a couple days later, shes kind of cold. So i'm like whatever, not worth my time if shes not interested.

Then she texts me Thursday night, I make her laugh a bit, jokingly say when we are meeting up for round 2. She says lets do it tomorrow night. Likely just meet up for drinks when our friends. Super casual.
Around 11, text her no response, try calling her once, no response. Oh well, meet some other chick that night and go home with her.

Next morning I text mrs flakey and just say "Tony Ditcher." Shes says i'm sorry I got super drunk, blah blah. Whatever I don't respond, she texts back a bit after and goes I don't work Monday night. So I say alright lets hang Monday then. (I should mention she is super hot, one of the hottest i've had, so I really would like round 2). Anyway she agrees, plans to chill Monday (tonight).

Monday - I text her this afternoon what time are you free? She says - As soon as I finish this essay. I have to do a bit of stuff so it may not be till later. I text back so what time are you thinking? No response. Text her at like 7:30 "So whats the deal?" No response.

So ya i'm a little annoyed, plenty of other stuff I could have been doing, as I had buddies that wanted to golf, and haven't seen my folks in a few weeks. Just looking for the best way to handle this.

A couple options in my head:
1. Ignore her, cut off all contact.
2. Text and her and tell her she messed up, and I value my time, and dont dig people that cant keep their word, so don't bother.
3. Wait for her to text me and, tell her #2.
3. I should mention she left her leather coat at my place the first night, so she is going to need to grab that at some point. Another option is play it cool - make plans either to meet up again, or for her to grab her coat, and then just not be home, and give her a taste of what its like to get blown off.

Any advice, is good. Keep in mind she is hot, and would like to get her as a regular, but at the same time I've got values and don't take to kindly to getting jerked around.

Thanks gents.

Don't worry she'll contact you to get her coat, but beyond that she's likely not all that interested.

You've essentially taken all of the wrong turns down a path that should have been fucking easy.
You say this but the rest of your post is completely contradictory. She's gotten herself into your head. Judging from this alone I'd step back, sort your head out, stop caring them go at her again but differently.
Casual sex = Casual Sex. Casual Sex DOES NOT EQUAL lets meet up with friends for drinks. To her this might have been a flashing light saying you wanted more. It's not a major indicator but personally as soon as "friends" come into the picture then it raises the "serious" bar a notch. I would have gotten her alone. Only time I introduce a girl to my friends is if she's worthy of girlfriend status.
Good attitude, another girl. Text once, call once. All good.
Okay so you pull and fuck another girl but still feel the need to inform hot girl that she's a flakey and you noticed it. To her this screams "neediness" and "oh I've got myself in his head" should have waited for her to text you apologizing and pulled out a DHV for yourself. Get her thinking she missed out as what you did made her think you missed out by her not being her.
Why not? she's reintroducing the conversation. Her flaking SHOULDN'T be a big deal to you because you can just go pull some other girl. WHICH YOU DID but yet are still thinking about her and she knows it.
Her hotness shouldn't counter into any process apart from fucking. The hotter she is the LESS chasing you should do. She'll have guys texting her constantly showering her with attention that you're also doing. You're a dime a dozen to her and it's boring.
Needy, needy, needy, needy, needy, needy. I get you need to know what time stuff is kicking off but to her you just look some plain normal boring AFC. She's "promised" you more sex and your chasing her around like her pussi is made out of gold.

You: What time are you free? < She gets this text and thinks "so he's free all day, guess I can do some other stuff and put him on the backburner"

Her: As soon as I finish this essay. I have to do a bit of stuff so it may not be till later. < This means "Some other people/guys have offered to see me a swell and that seems more interest. I'll probably flake."

You: So what time are you thinking? < You're giving her ALL the power. You should have text something like "fair, I'm free after 9." It's meant to be "casual" but you're making it serious and thus scaring her away.

You: So what's the deal? < She looks at her phone, rolls her eyes, puts it back and gets back to whatever she was doing. Most likely sucking on some alphas cock.
Sorry mate but the only person you should be annoyed at is yourself. Anything to do with sex, pulling and women = YOUR FAULT. That is the way world works for a man. If you don't like being jerked around then don't put yourself in a position to be jerked around. First of all stop caring, it makes things so much easier and whatever you have planned DO IT! Even if she texts you saying she's soaking wet and gagging, tease her, keep her waiting and go back to what you were doing. She is/did. Think about it. You're on the back burner for her, a backup incase all else goes wrong and she has to sit inside and be bored. Flip it around, make her chase you. If you have plans with mates then do them, same with family. If your busy, she's more attracted to you.
Do this. She'll probably text you saying something like "Lets do round 2..." and attempt to make you do all the hard work. Flip it around, make her chase you. Something like "Sounds good, I'll let you know when I'm free this week"
I only ever do this when I have 0 interest left in her and don't really care. She'll just roll her eyes and either ignore it or text back "Alright, chill. It's just casual." You don't own her time nor her and you/she made it into a "drink with friends" so she can make it less of a big deal.
Nope. Just ignore what she did. Her flaking should be no big deal to you. It'll drive her insane, she'll want to be a bigger deal to you and will thus dance all over your cock, lingerie, blowjobs, deepthroat, the lot.
Don't rely on the coat thing. She most likely has a wardrobe full of coats and such. One loss isn't a big deal especially as she's "super hot" and can convince some AFC to buy her one. She'll probably want it back but don't rely on it.
Mind games are for girls to play. Men or at least real men, ignore them and get what they want. Pussi. How exactly would you fuck her if you flake on her? Women have the power to flake because every guy wants to fuck. She has a pick of the litter, not you. Stop thinking emotionally, think logically.
The problem is is that you're allowing/setting yourself up to be jerked around. You said you both acknowledged it would be a casual thing but you made it into a bigger deal by being needy. Casual sex should be just that, casual.

I don't even get lairy if my girlfriend flakes on me. I just find something else to do. People are busy, flaking happens.

Either way, yeah she's not interested as long as you chase her as much as you have been.

Ok, I appreciate the advice.

She just texted me "Hey Sorry about last night. I definitely want to chill though soon if you still want to."

Whats the play here?

Just text her back chill and casual.

Something like "No worries little one, ended up having a good one. I'll let you know when I'm free soon"

Then wait till she chases. If a girl flakes then it's her duty to propose a new date/time. "I definitely want to chill" is code for "Lets see if you chase me more."

With "No worries little one, I'll let you know when I'm free soon" you make it not a big deal, you seem busy and such.

I second bascially everything that BITmixit has said.

You could even throw in an AFC joke as a DHV.

i'd start the text with something like "I'll tell you, my front step did get a little uncomfortable around 3am but I persevered and waited all night."

As long as she would recognise the joke.
