This sounds very sad and I have no idea how old you are but as Ive lost two husbands and married 3 times it sounds like the relationship was not at all what he wanted, I cannot imagine wanting to shut out anyone during such a time. AS painfull as this will be the last thing you want in your life is a boyfriend who disappears when things turn bad. If he truly loved you he would be running back to you at every moment he felt down, I notice no one wanted to express there thoughts. This is harsh but he is clearly is not into you as the movie says.
He is correct, you do not deserve this treatment
