Tigsy that's awful I'm sorry. I agree with Kin's email suggestion, I always write out what it is I want to say, helps me get it all off my chest and onto paper, and to focus my thoughts a bit, there's something cathartic about it.
I do think, sorry, that if he could end it over an email then either he's not the person you thought he was and would have overreacted like this at some point eventually, or that he had actually made his mind up to end it already (for whatever stupid reason) and this row has just become an excuse to hide behind. There is a further possibility, which is that he's just overwhelmed with the moving in together stuff and that he still does want to be with you. But for me, unless he came to me of his own volition saying that, apologising for the hurt he's caused, and being quite clear he would and could never do it again, I don't know if I could forgive and go back to how things were. I think once someone behaves like this, and finishes things almost on a whim, it's incredibly hurtful and very difficult to get over. Will be thinking of you.
And just to endorse what Juliette says (with my lawyers hat on) pull out of the sale if need be, and if it's not past exchange, even if just to give you some breathing space and you put it back up for sale in a couple of months.
Hey
. see, this is what I hate about texts, the potential for misunderstanding. So, when he said before (I'm probably paraphrasing) his feelings had changed, and he was sorry to hurt you, that he didn't mean 'I'm finishing it, sorry cos I know you will be upset' but more that his feelings were changing (deepening?) and he was sorry if you were upset by what you might have perceived as him backing off but wasn't?
Can you meet with him for a drink and discuss it? It does sound like possibly just a horrible misunderstanding. But I would be wary that he did initially mean it as it sounded, and he's now backtracking, but that's me being cynical (I am in that sort of mood, was actually half-hoping earlier C would text me and end it - I don't want him to, but I am fed up with the limbo, and in some ways would like to be put out of my misery. But I won't end it myself because I still like him lots, I just don't think he likes me...meh)
