An Experiences of meeting foreigners (Making the subject and object both plural better represents the stories you are telling.)

It is so amazing, that I have met two foreigners in Taiwan this week.
One is come from England, and another is come from Germany.
The first one who comes from England is a mix of African-Indian.
He was here for getting working experience while he's just 17 years old.
In the beginning, I didn't really want to go out with him because he was so rude to me when we chatted online. But when I talked to him face to face, I thought he was not really a bad guy.
So I went to watch Jurassic World with him next day.
I was always trying to be nice to foreigners because I treated myself as a representative of Taiwan. Unfortunately,I was so disappointed with people who took your my kindness as granted. (You are talking from the first person perspective about yourself so "my" is more correct here. "your" is incorrect and awkward, but still easily understandable.)
Of course you were going to back your country after few days, however, you didn't have to treat me so rudely by telling me saying, "I am going to forget about everything with you in Taiwan." (This could be said with a compound sentence like this. It is more conversational and fluid, but not necessarily more correct than how you did it. You start the second sentence with "However" which operates as a conjunction in a compound sentence. "saying" is a more common word to use when directly quoting someone. "telling me" is more common when you will be paraphrasing what was said.)
I felt so hurt when I heard about it that, but I also knew I have done nothing wrong.
That was why I got recovered from the sadness quickly, and thanksed to my good friend who cheered for me also.
If you ask me, "Do you regret for going out with him."  
The answer is no , because I have had lots of fun and learned lots of things from him. such as culture, food, religion and so on.
I think we probably can't be friends anymore,and I doubt whether or not the friendship between us is real. or not.
Confucius said, "When I walk along with two others, they may serve me as my teachers.
I will select their good qualities and follow them, their bad qualities and avoid them."

The second one is from Germany, and he speaks perfect Chinese.
I think he must have worked hard with at it, so I respected him a lot.
We ate the ice cream in a building with old western style architecture which was rebuild as a cake shop.
We shared about our life experience and philosophy and had a good time..
I really like him and hope he will enjoy the traveling in Taiwan.
