I think numbness has gone.
We had a lengthy email exchange the other morning. He clarified some of the things he had said. The bottom line, though, was that the message wasn't much different. But not quite as bad. He said he didn't want to talk on email. That he still loved me. That he still wanted a future with me. Stuff and blah... Would I still go over for the weekend. I spoke with my friends. They were fine and said I ought to go and sort it out.
On Friday night I had a lovely night away with 'the girls'. He went out with some of his colleagues after work.
He texted me yesterday morning to ask if I still wanted to go away for the night and that he did. I said I would and that I'd grab some stuff.
Then he texted again about half an hour later that I should probably leave it and go over Sunday (today) instead. I asked if he was sure, he said, yes, he had something he wanted to do and insisted.
I said I didn't want to do the journey twice in one day, and he said in that case, I could go over later last night and I agreed.
So I got there about 10. It was rather awkward. I asked how his day had been. He said he went into town and met 'a friend' in a nice pub for a drink. Then they spent the afternoon in the park. Then they went out for dinner. I asked if it was someone from work. He said yes, but didn't elaborate. I didn't ask.
He kept his phone with him all evening and kept checking it - he's never done that before. He barely spoke to me last night. Slept on the sofa that's in his bedroom rather than getting into bed with me. He didn't speak to me, kiss me, or touch me, or hug me, even look at me!... Nothing.
THis morning, he again said nothing to me, went to the bathroom and took his phone with him.
I got dressed and when he came back in I just stood up and told him I was going home. He shrugged. I picked up my bags and said "bye". He said nothing.
By the time I got home, I'd had a text and an email from him telling me not to contact him and that he wouldn't read or reply. 
Bottom line is. He either went on a date (wtih someone from work) yesterday, or he wanted to make me think that he went on a date (wtih someone from work) yesterday.
Either way, I can't be doing with that.
I've blocked him. It's over.
