ll give you a quick rundown of the story so far:

We met through a friend on a night out. Instantly hit it off, there was no awkwardness, we danced and shared drinks together. I got her number and planned to meet up on another night.

We meet up with all of my friend and hers. Again get drunk and have a good night. We kiss quite a bit that night and a lot of kino.

We also went out a second time a few days after the above. Same happens we kissed, this time she agrees to go out for some dinner with me.

Dinner date went perfectly looking back at it. No awkwardness, lots of jokes, some lines, constant smile on her face and lots of kino. I take her home and this is the point where I turned into an AFC. I dropped her home, hugged, and had the perfect opportunity to kiss her (this time whilst being completely alcohol-free) but i dont. This was a huge mistake because everything was right for it.

Anyway its all fine, we are in contact everyday then she i go over hers for a few hours but when i turn up she realises she has important uni work to do for the next day. So i say i can leave so she can do it but she says i can stay so i do. But as shes doing work, theres no kino, conversation isnt going so good. We hugged and i left. Now whenever she texts me its always very closed, she doesnt try to keep the conversation going. I havent text her in a few days either, she hasnt text me.

What shall i do? Wait for her to contact me? I think i just completely crashed at that last time i met her

Shes probably confused,look at things from her perspective and you'll see what I mean.

Try and invite her over for a night

Sounds like you've been doing a great job. For the part about her acting cold to you, I'd suggest the line "Why are you being so cold to me?" I know its sounds kinda AFC but it's worked 5/5 times for me. May not work right with you but it's worth a thought.

I quite like her so i dont want to come accross all needy and insecure by texting her constantly. Its been around 4/5 days since we last text.
