Cold treatment.
Take it as if this person never existed, just a dream, the dream woke up and life continues as usual, do not care too much, no one will be particularly concerned about a dream, and when the dream woke up, the memory of the dream is particularly fuzzy, and even sometimes can't remember what happened, take it as a sad dream.
While the process of the dream may be unforgettable, the ending of the dream is sad, just as a sad dream, let it become the past tense, do not be too obsessed with a dream, it is not worth it. Why waste your time and feelings for someone who doesn't care about you, that may be what he came to mess with you for.
I don't know how he thinks, anyway, don't let him get away with it, I left him life is still the same to continue, in this world, there is no one away from who can't live, even if the loved ones passed away, we still have to live on, so why be sad for a person who is not a loved one again.
Calmly deal with such a situation is the best choice, do not let him hold your nose, what is his say, he wants to come close to you to come, want to go on the go, then directly let this person disappeared in your whole world, he is also just from your whole world pass by and, that he has been passed by, to go to the time to graciously let him go well.
Don't be attached, our life process will meet a lot of such passers-by from our side, if every one of these people are very sad, that life is not happy time, sometimes have to be decisive. It is better to live a happy life.
The future will have to be careful of this kind of people, bright eyes to see clearly, do not fall into the trap of these people again, was cheated more or to learn smart. Don't be fooled by this kind of people every time, it's too stupid.
