I have this female colleague with whom I am very close to for the past year. We used to have breakfast together and eat lunch together. Our department usually go for lunch as a team and we usually sit together during lunch. But a couple of months ago things changed. She no longer have breakfast with me and she avoid me utterly during lunch. She either spend time with other girls or other colleagues. When she has the opportunity to sit next to me , she sits with other colleagues instead. Even if by chance we sit together, she will hardly speak to me. Instead she will make small talk with other colleagues and the other girl, ignoring me utterly. Even if I speak to her, she will give 1 sentence reply. But still she talk quite alot with me during office hours. While I enjoy talking to her during these hours, it is cutting into my time at work.
I just do not know why she avoid me during lunch?
