Hello. I think I know the answer to this but I'd like some advice...

I've been recently interested in my coworker. We've been viking and talking and I make her laugh and she seems to flirt with me a bit.

I like to read on my lunch break and I Recently was reading a personal favorite of mine and she asked me about it. We talked a bit about it and she seemed interested in the book.

We've been talking and flirting when we're both in office (every other week) for about a month and a half.

I was recently moved to the opposite in office week than she was and I didn't find out until Friday after she had left for the week. The new schedule would start before I would have seen her in person again.

I had just about finished with that book so I wrote a note in the cover and left it on her desk. (I have another copy at home).

I told her that I left her something for next time she was in office via teams. She went in the next day (on her work from home week)and sent Mr a message back calling me sweet and used excessive exclamation points. She had heard that I was moved to the opposite week and she said she was disappointed to hear that and she would miss our conversations. We talked intermittently on teams that week and promised to keep in touch.

I was on vacation the next week and I stupidly added her on snapchat. Or at least I think it's her, I don't have her number. This week I messaged her on Tuesday and didn't get a response until Thursday where she said that she started the book and that she is enjoying it. She asked me how I'm doing. I responded an hour later and she never hit me back.

At this point I think she has lost interest in me either due to me adding her on snap weirdly. (My dumbest impulsive adhd brain). Or she is just not that into me and I misread signs. I know she could just be busy but if she was into me I feel like she would make a bit more effort. What do yall think?
