Hey so here the deal. I met a Estonian girl at work, she is doing an undergrad project. I started to play hard on my social value first and succeded at some extent since all guys and girls talk to me, I go to have lunch with other girls regularly and so on. Next I started the 'purposeless' interactions with her just to talk and attract her with body language etc. She told me a couple times that Im smart but I never reacted, never threw compliments either, acted unreactive but confident. Eventually I got the stares and 'casual' encounters, you know she was there sometimes where I was out of the blue, body language was there also but never drastic. This is where it started to get tricky because I started to make her chase, completely ignoring her sometimes, this went on for some weeks and I'm not sure if I kinda screwed. Dude she was even validating herself sometimes. I believe she is hit on regularly because she is pretty though quite introverted. Dudes at work would stare at her without saying anything. I took my time making her chase because I have a GF and wanted to see if she is really integral inwardly and we could really match so the mess is worth it lol. Things got cold for some weeks but last friday after a small mingle she left and I caught her up to ask her out for a drink. During mingle I made her comply by asking her to tell us all a joke, which she did fantastic. She kinda doubted and said that she needed to pack cause next day she was heading on vacation but accepted easily. Then she literally asked 'text me'. I even said hey I know is weird cause we are at work and so on but she said no is fine. Next day bro! Damn I was ready to escalate but she was playing hard to get lol. Interacting and all but extra cold, and somewhat unreactive to contact. I kept it playful. I managed to make her say that Im interesting during date, and even made her repeat it, lol she really didnt wanna say it I saw it on her face but she did compliment back. I stopped the chase at some point and she started to invest more and quote. 'Am I boring you?' I said no I'm just tired of talking. 'You are so quiet' I took her by the hip said some shit and we both laughed, but she never took the hug fully, just cold. Then we took train, I didnt say a single word and when I was about to leave train she extended arm to hug, I wasn't gonna hug but we did. I just said have nice vacation, tapped her leg and left. Now Idk if I should chase her just send a playful msg closing with a hope you have vacation or if I should keep it cold until she is back. I was pretty clear saying that I like her and why I like her over other girls/people to hang around during date. She was just receptive but, once again, cold. She may leave the city if she doesnt get work in September but damn I want that girl for GF, I really like her, wouldnt mind to take her with me for some months to see if it would really work. This week I will go out with another girl just to shake it off a little bit but feel pretty stuck. Some advice and previous experience is always welcome. Peace out!
