in fairness we pinays are kinda bad with time keeping, i have learnt tho that here when they say 3 it's 3 and have managed to adjust to that. maybe the reason why he is so strict at the mo is coz you are still apart and he cherishes the time you spend online together and when you suddenly cancels to go out he must really feel pretty bummed out bout it.i am sure that over time when you are married this problem will settle down.
my hubby only wants me to tell him where i am if i am not back by the time i said i would so he does not worry, give him time and i am sure things will turn out ok.
