Search Results: confused about boyfriend

I'm an instructor and also an assistant for this guy. (I can't give details about my job) Let's call him Doughnut. I work alongside another instructor/assistant- Apple- and the three of us are at team. Doughnut has a boyfriend and once said that he's only into guys. So I'm a bit confused as to why he treats me as more than a colleague. He tends to leave lattes on my desk at least once a week. I started doing the same. He got Apple a latte just once. Other notable things are, whenever he wants each of us to choose something from a group of options, he tends to let me choose first. Also, when we leave work, we go together and Apple doesn't come with us. I ask her if she's coming but Doughnut never asks her. We also tend to text more as the two of us, even in our group chats. Lastly, once a day there's a task we need to do outside our work room, and he tends to ask her to do it most of the time. He is kind to her, but I feel like there's some kind of favoritism going on, although I'm not sure because I don't think these are clear signs.
