Well, I have this coworker who for some reason caught my attention (not romantically) and we started talking until I invited her to share lunch, But in the end we didn't do it because she was busy, but she felt bad about it, so when we left work she invited me to have ice cream and we took the opportunity to chat, and over time I invited her out several times, to have bubble tea, coffee and even to the cinema. But then I asked her out a couple of times and she didn't say anything to me, not even a negative answer and when I was the last one to say something I didn't speak again until The other person tells me something, (which has made me lose contact with acquaintances) but I also don't want to sound insistent or annoying if she doesn't want to talk to me. Did I do or am I doing something wrong? This kind of experience makes me want to have no more friends besides the two I have.
