Right so I was getting with this girl who I knew liked me a few months ago, people thought we were going out but we werent lol, then I made a huge mistake and over-invested in this girl, got given a LJBF from her, so I froze her out and didn't reply to her text (she kept texting me after i f*cked up of showing too much I interest which I take it is a good sign and said stuff like "I really wish I liked you omg I hate myself").
Anyway so yeah had frozen her out and forgotten about it, then the other day she texted me randomly like:
"haven't spoken in a while how are you?

xx"
to which I took my time in replying to so I come across as cool, saying: "hey _____ yeah good ty u?"
her: "you never replied to my text ages ago

(((((( you have a good new year?"
me: "oops yeah been super busy, why you miss me then

blah blah"
Her: "haha it's cool, nah actually I thought you were ignoring me

where did you go? Blah blah"
So now I'm wondering what I should do as I know I still have some feelings for her but she is not ready yet so I need to create a chase, what should I do?
Cheers
