Dear Diary

Dear Diary,
It was 14th April.Something happened in today.Yesterday,because of music,my boyfriend and me angried with each other.Today,when i signed in my Chinese Facebook,I saw some messages that he gave to me.He told me why he was angry and said sorry to me.When i listened his words,i was a little moving.Athough what he said that i didn't agree with him,he still worried about me and toleranted what i did for him.In the classroom,i can't type chinese,so i decided to reply him when i went back to hostel.
One hour break in the noon.I had my lunch and then went to bed to have a rest.It was time to get up and went to our class.I recieved his message in my cellphone.He said he hoped me can happy everyday.I didn't know what he meaned,but i knowed he was angry and i must did something wrong.When i went to classroom,i first signed in my Chinese Facebook and asked him what happened.He said something about equal and in order to don't hold up my class.He didn't want to tell me the reason in my class time.I was a little angry that i didn't have mind to listen class.The teacher came and sit next to me.I closed my computer and listen to his class carefully.The class was moving on.I couldn't opened my computer so i couldn't reply what my boyfriend said to me.I recieved a message in cellphong,it said"Why you have heart of steel."
I almost to cry,what's he means,why he said that to me? what did i do wrong?
The teacher left on my side and i opened my computer,it was many massage on my Chinese Facebook.Everywords like a pin pricked my heart.I didn't have strength to argue with him,I only did what i said to me.
The class was over at 5 o'clock.I waited for him at the bottom of his hostel.He gave something to me and we had a talk.Everything was on the light,it was all misunderstanding.
In the evening,we watched movie together,we still quarrel,but we all knowed that we love each other.Dear diary,he was my love,i didn't want to hurt him again,i still can't control my temper.I always agrue with him.I didn't want to do that,what i should do?Can you tell me?
