If she knew he was in shock by his friend's predicament (after contacting him first)... how come that didn't carry over to being the first possible explanation for him not replying later on?
I'm sorry... but overwhelming circumstances tend to trump routines... and are usually expected to throw routine out the window for a bit as well.
Strikes me as odd for someone to expect their bf to adhere to a routine when it's obvious they are in emotional distress.
That's like expecting bf to call her during a funeral because that's about the same time he normally calls her.
So what if he didn't respond? She already knew he was in turmoil after contacting him the first time. Seems to be that she doesn't understand that routine is subject to circumstance --- in that routine is conditional and when the conditions/circumstances change... so do routines.
I hope she learns to be more flexible... knowing how to 'go with the flow' is a must for a successful relationship.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
