She never mentions him, even if talking about days off or vacations etc in the past year or so, which I didn't pay much heed to at first, as some people are just more private. But recently I discovered that it seems to be just me who is excluded, who she doesn't discuss him with, which makes me wonder now if there is a hidden distrust or something.
I'm confused because she is always seems very warm and friendly to me, she messages me a lot, sits beside me and she is always keen for me and her to hangout, go for coffee etc. I'm assuming she has no romantic interest in me as she is in a relationship, which means she must have a secret dislike to me or not fully trust me yet.
Any ideas?
