Went and stayed at my partners over the weekend as was feeling low due to stuff going on in my personal life. I had some bad news on Friday too. I told my partner this and I went over Saturday. When I went round we were talking and she said to me that she had been complaining about me to her work colleague. I said oh that's nice, thanks and she said I'm sure you moaning about me. I said well no I don't actually. Then we got onto the subject of my bad news I received. I began discussing it and she joined in. Then she flicked on the TV when I was half way through talking and said something like have we watched this? I got upset because I said this is a big thing and you're acting like you're not interested and don't care because you just talked over me and said that.
Aibu to be upset with my partner? Given they knew how upset I was?
