Mourning is absolutely the right word for it. It's the death of a relationship and of an era for you. Just because the individual isn't actually deceased isn't going to make it hurt any less.

For me I definitely felt a lot of that, along with anger and betrayal, sadness... Frustration.

If you want to vent about it feel free to dm me.

I hate that I don't have friends like that anymore, even though I know I did the right thing. I sucks so fucking much
