So for all of you who have been following my story, I met this flaky girl, we went on 3 dates so far (all at a bar, lol, although she was always sober). Last night we met up at a bar, and I decided to start showing a lot of interest by kissing her; she reciprocated.
At the end of the evening, we went to her place and made out passionately for an hour. It was so awesome, WOW. she was telling me that she wanted me to come over for breakfast the next day, and she wanted to see my place on Sunday. I told her she was pretty when we were kissing, and everything was going great. I texted her when I got home calling her "sweetie."
The next morning she cancels breakfast. I text her the following:
Me:"I would like to see her again, shall we make plans to see each other in the afternoon?"
Her: "Yes"
Me: Let's see a movie today at 3.
Her (4 hours later): this evening is probably better
Me: Let's go out to bar X. I can pick you up at 8?

Her: I am not feeling so well
Me: No worries. Get better soon!!
Her: Idk, maybe we can go see a movie. I will see how I feel. I will text you later.
Me: That's cool! Talk to you then!
I haven't heard from her since, but obviously the "I am not feeling so well" part was a lie. Obviously, I put too much interest in her, but I was thinking that since she was so into me, it is safe to be more assertive (cause I really like her, and when a girl likes a guy, no games are necessary).
F***, where do I go from here? Obviously I cannot text her or I will reek of desperation. Should I just go NC for a while till she contacts me again?
Thanks in advance, everyone! I truly appreciate everyone's input. Thanks a million!!!
