got this chick, spent a week always with me, was sick still stayed the whole day with me, said she was going to spend only the morning with me, spent the whole day with me

She is extremely shy and introverted (but 8.5/10 and nerdy, my type at its best) and so she doesnt sent out those big IOIs and since im also a pussy, virgin and a bit shy I am also having a hard time making the move

My friends say she is into me all the way, I am overthinking it. She spent a whole week everyday with me from morning till night, we watched movies, we visited places, did random shit had fun all the time, we connected and vibed awesomely, she even said she never opened herself up to a guy like this before, after this week there was christmas and such and we last saw each other on friday, then tuesday I called her and she didnt answer so I texted her and she said a big double text reply why she couldnt pickup her phone and bla bla why she couldnt meetup with me

I said np we'll set up someting next time, I called her today and just went like "hey, all good? great, tomorow I have to lunch somewhere, wanna meetup to lunch and do random shit in the afternoon?" then she said "yeah sure" and I said, "tomorow morning i'll hit you up and talk details"

Thing is, im already overthinking "well maybe she just want friends and its better to not force anything" but then im like "well, to find out just try to kiss her dude" then im like "how to kiss her? car? movies? alley?" then im like "well maybe she just doesnt want do" and repeat cycle.... any tips & opinions?
