I can say that he does not deserve you. There are some bad people in this world, can you expect them to be good and behave like saints, No they will never be.
Many times we expect things differently and feel sad when things do not go the way we want. This should not disappoint you, rather it should be learning that not everyone can be trusted. The person who made you cry will face his karmas. You do not have to bother. Just take it as a bad experience and move forward in life. Focus on your work, studies, or whatever you do. That will help you move away from him easily.
