如何令一個既鍾意你卻又怕對你許下承諾ge男人願意跟你發展情侶關係?

If you both have feelings, give each other time and let stay friends until he returns back. I think he is trying to be a gentleman and not wanting to tie you up while he is away. Also, he may want to focus on his study, it can be a lot to give up if he has to make it works.

It is hard to last a long distance relationship, however, never says never. He may feel exactly the same as you do. You should let him know your feeling and don't give him any pressure.

I hope you both work out at the end and good luck.

佢唔想下巴輕輕都係為你好啫，一陣佢做唔到你話佢口心齒咪重衰。
你而家只可以等佢讀完書返黎先再算。

１改変自己２用書信來往助他解決心事
最后　時刻成為他最密切互動的人。
