Hello again Hush
Yes, it's a horrible time isn't it? As you say, it's not what I wanted but I have no choice. It must be so difficult for you having to see and speak to your "D"H. There are times when I (inexplicably) yearn to see and speak to my STBXH, but I know it would set me right back to the beginning emotionally, and I absolutely know I could not go back there again. Without wanting to sound too dramatic, I really don't think I could make it through a second time 
I often sit and wonder if those b&*@@tards ever have a single flicker of guilt or remorse or, indeed, if they have the slightest inkling of what they are putting us through? And for what? Love everlasting at the other end? Off into the sunset together? I just found out yesterday about a colleague whose "D"H has done the same thing and upped and offed for a much younger OW. Another family torn apart and a woman devastated because of a selfish pair of ... there are no words!
I've found, like you, that friends have been an absolute lifeline. They are there for me and listen to me rave and rant and weep. They have buoyed me up and helped me to look ahead and see that my future will not be as grim as I think it is. STBXH will not be in it, but the void will be filled with countless, far nicer and much more worthy and decent people. People who care and whose respect and good opinion I value hugely. Much better than one selfish, entitled middle-aged man. When he dropped the bombshell he said he hoped we could "remain friends". The more time goes by, the more outrageous that statement seems. He hasn't a bloody clue what the word means ... Anyway, keep seeing friends and family; they are the ones who will count in the long run.
I'm off to The Island (if you are South Coast you'll know where I'm going) today to visit a friend I hadn't seen for a long time. I texted her once, out of the blue, in a fit of despair and she got straight back to me and has phoned and texted ever since to see how I am. No mention of the time that has elapsed, just care and concern. Now, that's a friend!
Yes, poor old dog certainly didn't live up to his master's expectations. STBXH started off with this fantasy picture of a master and hound relationship and what it would be like. He bought the hound - £500 - over my protestations and then found over the years that his fantasy was being eroded. The dog was messy, cast hair everywhere, retrieved everything and anything and left a mess in his wake, developed flatulence and crapped all over the garden. STBXH became tired of the dog, found him irritating and I think began to actively dislike him. Didn't turn out to be the dog he thought he should have been, so he was quite happy to abandon him. I now feel some kinship with the dog; our situations have turned out to be quite similar - well, apart from the flatulence and crapping, but give it time 
I'd better be off and get ready for my voyage. Take care and keep posting.
