We met each other working for a common project. She is usually nice and kind with me, going to the extent to help me solve problems she dind't have to solve or help to solve. I have asked her out for coffee twice. First time I achieved to go out with her, but it was difficult and she sent me signals of not being interested. That time when I asked her out next day, she text me back telling me that she will be very busy that day, and that she will contact me back next day to coordinate with me. That never happened. Next week she text me but for reviewng work topics (a topic that she can handle or solve by herself without telling me nothing), so I interpreted this as an excuse to get in contact with me again. So I ask her out again and she apologises for not contacting me back because was very busy, and ask me if I can go out next day. We went for the coffee next day.

Next week it was my birthday and she unexpectedly sent me a greeting text. It was strange because at first, the tone of the message appears to be work related, but then she told me that it wasn't anything related to job, and that she read at the Office screens that was my birthday, so she wanted to congrat me. Next week I go out the country for vacations during two weeks and I have recently returned to the Office. I bought her some souvenir candies and give them to her as I returned, asking her again to go out for a coffee, but I've received the same treatmen that before. She told me that she will be very busy and that we will coordinate in the week (that was at Monday). Friday came and anything happened, so I text her back and told her that I won't be available to go out for a coffee early on the morning, proposing her instead to go out for lunch. She replied that "it may be a good idea", so I told her I know a good place to eat pizza and invited her next week. She haven't read my messages and I know she does it on purpose because she was online for two hours more with her status set on "disponible".
