Just now she was waiting for me and when I was done I found out she started an online chess match. I told her let's go as I was done but she said she hasn't finished the match yet and told me to go to the library first. After she came back she looked upset. I asked what's wrong but she said "nothing" even though something was definitely up. I asked her a few more times yet she said don't want to talk about it.

At the same time she still does things for me like making me food etc. What's happening? I'm so confused
