Jo, you have always seemed like a very sweet, nice person who looks lovely in all the photos I've seen.
I am terribly sorry that this man did what he did. You deserve much much better - truly.
I am now going to say something that may result in some of the members of this board wanting to have me neutered.
I had several relationships in a row end badly - all in about the same amount of time, all for the same basic reasons, and all with the same basic type of partner. I didn't change this cycle until I really started searching out the reason I was picking these people. Yes, many men are pigs, and I am not apologizing for them or making their actions the fault of someone else - and the fact remains that what all my exes had in common was that I had picked them!
I suspect that when you discover what it is that appeals to you about this type of guy (since you say that it has happened before) - whatever it is - you will shift it and create a wonderful relationship that is worthy of you. There is nothing "wrong" with you - you are wonderful. You may be able to improve how you pick men - this will involve looking at what you are attracted to, and why.
I strongly recommend If the Buddha Dated by Charlotte Kasl. It's a great book.
And by the way, say the word, and I'll kick his ass.
