If you could take the time to read all of it and give me advice / help on how to proceed I would greatly appreciate it!

I went on a date with this girl in my chem class two weeks ago and she was really into me. We kissed, lots of kino and IOIs on both our parts and we had a great time. Next week came we were still flirty and having fun hung out for a few hrs on wed and I kissed her goodbye. Then the next week she went cold and wasn’t flirty or touchy on her part (i dialed back my flirtyness and kino to reciprocate) then she was ignoring my texts for a week (initially she asked me a question and i answered it 5hrs later and then she didn’t respond. I texted her the next day again to push for a hang out – it was a cute flirty text – no response, and then i texted her again a few days later and still nothing). This last week she was cold again but we hung out after class on wed for a few hrs. I didn’t kiss her but reinitiated kino (holding her hands when doing “the cube” ) etc. – My main focus was building rapport that day – After the cube she said she was hungry and asked if i wanted to get food, her treat, so I went but didn’t get anything and we hung out there for another hour. When it was time to go I gave her a hug.
She texted me later that night but it was brief nothing flirty. We set up another hang out to carve a pumpkin on monday so long as she finished all her studying in time this weekend (two exams she’s been stressing about for the past week). She’s not a big fan of technology…doesn’t use FB often or attached to her phone.

I’m going to text her on Sunday with something witty like “Those innocent eyes, those juicy lips, a great smile, that awesome bod, so hot! But enough about me, how’s that studying going?”
Then follow up with
“So I still going to be taking your pumpkin carving V card this monday? ”

Hey buddy,

I don't know the whole background and i might made incorrect assumptions but this is what i think:

In the beginning you and her had fun. She enjoyed her company. But after a while she found you were pretty easy to 'be conquered' and now you are texting a lot/too much. At this moment you are not a challenge anymore, and you are becoming AFC.

I would suggest to spice things up a bit. Stop those boring textmessages (i.e. how good she looks, how her eyes are...), but tease and neg her a bit. You are acting like an AFC. You are no challenge anymore/Alpha-maleIf you get back in the game, don't compliment her about her looks!!!?? Give her a compliment about her character and how well you and her connect..

Hope this works mate
