This is what I think OP.
There may be several reasons why this man did this disappearing act. e.g. 1. Felt suddenly frightened of the emotional intensity (that he helped to create
!)and felt he had to run away. 2. Was led by his trousers and immature romanticism to pursue you and then realised it was not what he wanted. 3. Really manipulated you, player-like And so on....
On one level you may never know, but I think all these kinds of scenarios, and others are possible. Most of them point to emotional immaturity, even if some of it may be also exploitative by him, whether consciously or unconsciously, especially given that you are feeling quite vulnerable
.
So, on one level, I agree with whoever said - move on fast - its not about you, its about him. However, i do recognise that you may be feeling pretty roughed-up by it. He kind of devoured you sexually, you shared this and really personal things, and then he spat you out kind-of-feeling? Really horrible and
.
I think there is no ultimate protection around this as there is always a risk in starting new relationships. However, I think one can learn to protect oneself also e.g.
Get to know someone as reasonably well as possible before over-trusting.
Taking things slow.
Being real and honest with oneself about the qualities and weaknesses of the other person.
Not overly romantisising them or ignoring red flags.
Listening to gut instincts.
Not allowing oneself to be swayed by romantic fantasy and sexual intoxication.
Being honest with oneself about one's own value and strengths and what one really wants, as well as one's own vulnerabilities.
Even doing all the above, you cannot fully protect yourself - but you can protect yourself from the worst self-deluding fools and damaged men. And I think it helps you to stay more in rightful control of what is happening in your own life, rather than giving it over to the "man".
It is him, not you. But did you have some illusions about this man that were not supported by the reality of what you knew about him e.g. from your past?
Forget about him yes and move on, count yourself lucky he lives in another country

p.s. I really thought about this OP, it helped me clarify my understanding with some of my own bad and sad experiences ironically, so thank you.
