My problem is with a girl, we started out just texting. It was always sort of flirty with smiley faces and what not. I wont go into great detail unless you want/need or what's necessary. But we recently met in person, I spent around 7 hours at her house watching movies and drinking beer with her sister and friend. Her body language was extremely positive; we were on a couch for the majority of the time, and she had her knees on the couch (bent towards me). I did find reasons to touch her a few times and she never pulled away.. in fact she probably wouldn't have pulled away if I didn't first. After it got really late (midnight) I could see she was tired so I asked her if she needed me to go, so she could sleep. And she told me she did because she needed to get up early for work. So, I gathered my stuff and to my surprise she came up and hugged me. So all was well until we set up a second date. I told her that my sister wanted to meet her and she responded positive to this. Saying "alrighty, I'm down for whatever " however on the day of the date, I tried texting her if we were still on. I got no reply so I tried calling and got the same no response( we do have a past history of flaking on one another, before we met, but this is AFTER the first time we met, so I presumed it would stop). about an hour before the date was supposed to happen she texted me and said "prob not I have a lot of shit to do before I go to (another state) on friday." I was pretty devastated. I texted back "ok, it's cool, let me know when/if you want to get together next" to which she responded "yeah for sure". But I wasn't satisfied. I felt like everything up to this point was going so well. So, I texted her again " you know, the signals you send are really mixed you know I'm interested in you right? it just seems like sometimes you are really interested and other times you're not.. so it's really confusing me. and don't feel bad if you don't feel the same. It'll get me down for a little, sure. But that's life. I still wanna be friends with you and chill when we can." (up to this point it was a total of 3 texts to which she never responded). then I sent an additional text asking if she'd rather talk about it face to face, and again she ignored me. it's been 3 days since I've heard from her. I'm worried I might've ruined whatever chances I might have had with this girl. I really like her and I don't want to give up. I feel because of her initial signs, maybe she is into me, but wants to take it slower. Am I crazy? should I move on? In order to get out of my depressed state I came up with a plan to not talk to her for a few weeks ( giving her a chance to contact me) and if she doesn't, I thought about approaching her at her job. I know it's not polite, but I feel like I need to be bold and show her I'm serious while also telling her that I'll understand whatever it is she's feeling (whether she wants to take it slow or if she's not interested at all) and maybe see if I can just start from where we've left off. I figured I could bring a gift I got for her, that's about art which she's into, to show I'm not being malicious. I've been so depressed. I really like this girl. Any advice you can give me I will appreciate.
Sorry, I know this is long, but it's impossible to understand without context which is lost without elaboration ;_;
Edit: I'm a 23 year old male if it helps.
