Background about us: been with LTR for a little over a year (I'm 22 she's 19). I'm completing university in less than a year and am looking at starting a job offering 90k a year. I'm athletic (weights cardio daily and good nutrition). LTR is just starting college, not very ambitious (has done poorly in highschool up until this year in which I helped her a lot), much of her success in the last year was influenced by me helping her (including pushing her to get her drivers license, try new things etc). She does not workout, slightly chubby, but still a 8/10 due to cute face, personality, age and makeup. She has lots of family issues, history of homelessness (due to no father in the picture and a mentally ill mother). I'm her first LTR (she was a slut before we hung out having slept with 10 guys by the age of 17).

Previous dread game success: Before my previous year of school began I broke up with her stating that I needed to focus on studies. After hooking back up she became less clingy, more supportive, and would have sex on request and initiate every time we hung out. Overall in the past year, besides the occasional shit tests, she's been supportive and overall good to have around. Recently she's been flooding me with shit tests and becoming more expensive and giving out less sex. Additionally I've been expecting her to improve herself more as I myself am ambitious and would like to be with an ambitious LTR.

The event: I told her to stop smoking about two weeks ago (in the past, gentle supportive attempts did not work). She did not smoke for a week (was being really bitchy for the first few days). The other day while we were hanging out she was being annoying and tossing lots of shit tests at me. I told her that I'm bringing her home because she's acting annoying. While driving her she apologized and confessed that she thought she was acting this way because she had a smoke at work today. I instantly told her that I wasn't going to see her for a week. Keep in mind, her whole family smokes, and her closest relative (her grandmother), who she lives with is a heavy smoker. After a few days of her texting me and me replying with single word answers, she showed up at my door after telling me she was coming here to pick some stuff up. She looked beautiful, did her hair, makeup nicely, and dressed sexy. (Looked like an. 8.5 at this point). She tried to make conversation with me and hug me but I continued to ignore her. She asked me to cuddle, I quickly said no and she began crying asking if I still liked her. After much silence I brought up the smoking thing in how I needed to know that she would be willing to work on herself for us especially since we've been together for a year. Because she failed the smoking thing, I told her I didn't trust that she would improve herself. She brought up the fact that she works a minimum wage job, doesn't workout, is bitchy and told me that she would work on these things. I told her I need space, and after sitting with her while she cried for a while I left and went for a run.

Am I using dread game properly? Part of me feels like I'm just being mean. Another part feels like I'm expecting to much out of my LTR and I'd be better off to just end it and look for another one or go MTGTOW.

TLDR: told LTR I needed space after she failed to do something that I insisted to her that I wanted her to do. Has many areas in which I want her to improve herself on, and I feel like her failure demonstrates a failure of a will to improve herself for this relationship.
