Is she interested or polite/friendly

Hey,

looking for advice from all of you more experienced than me. Sorry for big text but I cant make it smaller :D

Met girl in workplace few weeks ago. I knew about her for some months but I initiated contact with her few weeks ago. We are not colleagues. Both of us works on different department and we just bump into each other from time to time because our working schedule is not same and and we just share few specific places where we see each other.

I started conversation with her by being more casual to her because I am older than her. We started to chat during afternoons. If I could count it, it was more than 5 or 6 times. Sometimes for straight hour, once about hour and half. ​We have some pretty similiar hobbies and she later started talking more about her future, showed me her photos of things which she likes and what she saves for. I already knew alot of about her family and her personal live outside of company from previous conversations. For first i thought she is pretty shy without friend outside of online world (she told me that) but during our last chat she showed me her spicy vocabulary etc. We are pretty much matched with habbits, dark edgy humour, lazyness and alot of other things. We touched many different topics from work related things to family, future, opinions on other things, hobbies - except personal relationship topics like if you have boyfriend/girlfriend. She stayed with me over her break at least twice so we could chat..I dont wanted to pressure or force her to contact so I let her at least three times to initiate it by herself which she did. I asked her for her social platfrom which she agreed and showed me her name and later accepted friendship (its not *** or ***, but i dont want to be specific).

I texted her once with something meaningfull. Just my few cents on some show which she mentioned. She later that day replied without any hook back but with personal emojis. It would be forced to text her back just to stay relevant so i didnt stretched it by replying back.That was her day off. She came to work after two days and initiated chat with me for hour long conversation. I genuiely feel that we are so much mirrored in our habbits and flaws. I cant comprehend it. I can make her laugh.

When we departed i told her I am glad we spoke together again and told her lets see if we can meet on monday afternoon again? She noded with smile and we went to each other offices. During our chats with slowly walk, stay, walk, stay and chat.

I will be specific on things which i noticed.

- She told, how sleepy she is at home and in work. She told me: you are one the two reasons why I am awake in work. I was genuinely strucked by it and couldnt respond properly (i guess). I am shy.

- I told her that I trying to recognize which road she will pickup during her walking to her office so I would bump into her. She told that she looking where I am and sometimes noticed me to work and she dont like to disturb me.

- she showed me my name in email adressbook asking me is it you, right? We are not part of the same department email loops and conversations so we cant see our names/surnames. You just need to find it in adress book full of names.

What is your take on this, please? Is she only polite or am i picturing something in my head? I dont want to be creep or chase her. I genuiely like her for being very inteligent and my mirror copy in so many things.

Thanks alot for your time ​
