28 day -----Become better

I met a friend yesterday night，she is a very cute girl，and I have not seen her for a long time。After the dinner with my friend，I walked on the road alone。I saw her and said hello to her。She told me that she did not have a dinner。This is unbelievable。Because yesterday was the birthday of the Chinese god of wealth，we often have dinner with our friend or colleague in this day，and wish each other to get more wealth in this year。So when I heard that she didn't have dinner，I could not believe it。
I took her to go to a restaurant and ordered some food。She did not tell me what happend。But I felt that she had closed her heart。Maybe I made a bad decision，I never give her a little bit of comfort when we finished the dinner。 I hoped that she could solve her problems by herself。
God bless，I hope that she will become better when I see her next time。
(NB: This is very confusing, because you do not clearly distinguish between the friend you had dinner with in line 1 and the friend you ran into on the street ("road" is less likely, unless you are talking about a traffic artery  that connects two towns or two cities, "Street" implies a residential area.)). I'll give it a try.

I ran into a friend yesterday evening. She is a very cute girl, and I had not seen her for a long time (past perfect!). After having dinner with another friend (at least, I assume that this is what you mean), I walked through the streets alone. I saw her and greeted her. She told me that she had not had dinner (past perfect!!). I thought that was unbelievable, because yesterday was the birthday of the Chinese god of wealth, and we often have dinner with a friend or colleague to celebrate this day/on this day and to wish each other more wealth in the coming year. So when I heard that she hadn't had dinner (past perfect!!), I could not believe it. I took her to a restaurant and ordered some food. She would not tell me what had happened (common mistake: -ed on end). I felt that she had closed her heart to me. Maybe I made a bad decision by going out to dinner with her. I didn't comfort her when we had finished dinner (here, again, the original is not clear). I hoped that she would be able to solve her problems herself. God bless her: I hope that she will be feeling better when I next see her. Pugs rule!
Chinese version：
昨天晚上遇见了一位好久不见的朋友。她是一个非常漂亮的女孩。跟朋友吃完晚饭后，我一个人在街上溜达，遇见了她。她告诉我她还没有吃饭，这让我很诧异。那感觉就好像在圣诞夜你遇见了一个无家可归的小女孩。
我们去了一个饭店，点了一些吃的。她始终没有告诉我，究竟发生了什么。我只是感觉她在排斥着所有的事情。或许我做了一个很差的决定，我连一句安慰的话都没有说。希望她可以靠自己的力量解决问题。祝福她吧。

28 day -----Become better

I met a friend yesterday night，she is a very cute girl，and I have not seen her for a long time。

^-^ I met a friend last night，who is a very cute girl. I have not seen her for a long time。

After the dinner with my friend，I walked on the road alone。I saw her and said hello to her。She told me that she did not have a dinner。 (There is no need to add "a" here.)

^-^ She told me that she did not have dinner.

This is unbelievable.

Because yesterday was the birthday of the Chinese god of wealth, we often have dinner with our friend or colleague in this day，and wish each other to get more wealth in this year。

^-^ We often have dinner with our friend or colleague in this day……

So when I heard that she didn't have dinner，I could not believe it。

^-^ I could hardly believe. ( It's grammatically right, but this sounds better.)

I took her to go to a restaurant and ordered some food。She did not tell me what happend。But I felt that she had closed her heart。

^-^ I took her to a restaurant and ordered some food. ( take sb. to some place )

Maybe I made a bad decision，I never give her a little bit of comfort when we finished the dinner。 I hoped that she could solve her problems by herself。

God bless，I hope that she will become better when I see her next time。
