Search Results: giving a girl my number

So I met this girl on tinder and managed to get her to text me on whatsapp after like 5 sentences on tinder. Not to brag about it, but it just went so smoothly that it was the right thing to do (giving her my phone number). So I eventually we talked a little and I asked her if she was going out tonight, because we live in the same town. She said yes and we decided to meet up downtown. She brought a girlfriend and I brought two friends.

So here things went south. This girlfriend of hers HAD to stay with her friend constantly. My friends tried to start an convo with her girlfriend but she immediatly rejected them lol. I didn't quite know what to say because of this annoying girlfriend cockblocking me.

Eventually the girl says she was going outside but that she would be back. Obviously this was the plan of her girlfriend, she herself seemed really insecure about it. Couple of minutes later they come back inside but they stay across the room, as if they were trying to get me to run after them. But hell no, fuck thatn I just stood were I was for a solid 10 mins :'). I eventually walked towards her and tried do dance with her but she rejected me loool. Before they went outside she didn't. I'm figuring this girlfriend of hers gave her the advise to play hard to get or something, but I thought fuck that and left to another club.

I'm not looking for a solution or anything but I'm curious about your opinions. Who's fault is it that it went south?

Ok so me and this girl talks every morning and I thought of getting her number or well giving her mine in weird way. So I would say some stuff which would lead to "do you have your phone with you" and then I ask to see it and then call my own phone or text it saying something goofy "like hi I'm 'name' and I'm weird".

I don't want it to seem forced or weird, I want it to seem slick and goofy or funny.
Me and her are cool and she's easy to talk to and she's kinda weird at times but I don't know, I still don't get LIKE THAT but it would be a big step foward in my opinion if it worked.
Sorry for the essay

Every time I go there this girl just stares and does not smile. She doesn't show any facial expression. She was helping her coworker move a cart and she was coming by me. I didn't look until she started staring as she was moving the cart alongside me. She held eye contact and moved her head as she was passing by. Then the next time I use my card to sign into the gym and waiting for my friend to give the gym worker his number because he's coming in as guest. As I was waiting I see her under the desk and she's just staring at me. Another time she's giving these 2 guys a tour of the gym and she comes past me. She's literally talking to them and looking at me and holding eye contact. Why is she so intimidating towards me. I did nothing wrong.
