:hug: its the worst time, right after a break up. I broke up with my fiance after 7 1/2 years together (we split up 10 years ago this autumn). It was one of the hardest decisions I'd ever made, but we were, like you, two completely seperate people.
It really hurt like hell and it was so difficult to concentrate on things. I wish I had knitted back then. Unfortunately I didn't and it took me quite some time to get through it but I did in the end. It is way way wayyyy better to know now than to know later down the line after marriage or kids and have to go through a divorce.
All I can offer is :hug: :hug: and a sympathetic ear. We're all here for you, hang in there, you'll get through.
