好聽的分手原因可以是什麼?.

對他最好的方法是告訴他「事實」，雖然是殘酷，但告訴他一個美麗的謊言，對他來說是更殘酷。將你所想，所講，所感受到的一一告訴他，使他清楚明白到他不足的地方，但緊記著，盡量不要傷害他。無人分手係唔傷心的，但你要將佢所要受到的傷害減到最低。

P.S. 我想在此讚揚你的真誠，真的不受他便勇敢地告訴他，不要欺騙他，不要浪費他的時間。

無必要講事實. 對男人黎講, 你講乜野 "事實" 既理由都唔多聽得入耳.

你鍾意既, 簡簡單單
"我唔鍾意你, 分手啦!!"
"我覺得我地性格不合, 分手啦!!'
"同你齊, 你唔再比到開心我, 分手啦!!"
再瀟酒o的 "我地分手啦." (消失於佢既世界中)

Please kindly let him know the truth, as soon as possible.
Ya, he may get hurt and feel shocked, but better than just think an excuse and lie..
It would be a proper way to treat him good, let him know how you think, also the reasons

Just be honest with him dont lie. Tell him what you have in your mind. If you lie and he finds out later it'll make it even more worse. Tell him why you think that things are not gonna work out

直接講，唔好呃佢，如果呃佢你良心都唔好過，至少要俾佢知道分手嘅真正原因。
