My ex-boyfriend went from hot to cold. he used to have a heart, but now he doesn t even care about his 4 year old son. he said that God told him that we are no good for him. just last week he said I love you to his son and he misses him. and yesterday he said his son and i are bad for him and to not call him anymore. i haven t spoken to him for a couple of days cause he told me not to call him. but i called yesterday because i needed someone to watch out son so i can take my daughter to the emergency due to chest pain. he said to not call him and no he was not going to come over to watch his own son. its like he has split personality. he went from a very sweet person to someone who is just plain rude within a week. oh yes, i think he is paranoid and schizophrenia. i know he smokes and does marijuana.
