Thanks again for the help of this forum members.
Please translate the below into Vietnamese for me please (I would hate to get it wrong and for her to mis-understand me):
1) you are the only one I am in love with
2) I do not know how to prove to you but if I did have a girl friend, it would be very difficult for me to go on holidays by myself and visit you in Vietnam without her knowing
3) it is very hard to get time off with my work and it took a lot of persuasion with my boss to give me time off in May to come and see you
Your help is much appreciated. Thanks in advance.
