i think i took this a little differently... going to the roof and screaming "i am going to jump" doesn't sound to me like an attempt to commit suicide: it sounds like me like he is trying to guilt her into forgiving him.
the narrator seems to be a friend who is trying to convince him to come down and handle this in a rational way. he is aware his friend is likely not suicidal, but he is not going to call him out on it because his friend needs his support right now.
