plz changes his attitudes, i'm willing to do anything...

he finally left for australia for his NS training.. dun have the same feelings which i had last time when he left for taiwan during earlier march... though still feel abit upset but 3 wks very fast pass... actually had a quarrel with him before he left.. duno wat happened also, he juz bang the door & slammed the telephone down for no reason. i asked him & he juz said nothing... sometimes i really dun understand him, it seems like we are drifting further as times go by... his mood is always unpredictable... i almost break down everytime he treats me like this... i always hope that he will change better, treats me nicer, dun always anyhow vent his anger on me. felt so accused... i'm still waiting for changes in his attitudes even though i waited for 4yrs already....
