Sold out by a brother !!

I recognized a sister-in-law six years ago. I was very grateful for taking care of me when I was in Xia lingxiao, So I recognized it. The first and last one.
I dare not tell my sister that I am afraid of my sister, because it feels like a good wife at home, but you ran out again to pack two milk. It makes people feel uncomfortable.
However, in addition to the previous two years, the birthday cards and small gifts are presented to each other in the six years, and the remaining four years have not been carried out for various reasons. the contact information is also lost because of migration and other reasons. Besides, I have to be busy with my studies, so I have no time to contact her.
After four years, I had a message from the other party, and I also learned some information and contact information from my brother. I made a call and noted down her QQ, but I haven't played it for the second time, and I have never seen it on QQ. the contact is limited to this.
A few days ago, after my sister picked up my brother at the train station, she sent me a text message saying she had received the brother and my sister-in-law. I immediately fell asleep, and I never told my sister what I knew. even if my sister-in-law has been to my house.
So I am sorry for my sister. there is no way to explain it too much. It takes too long. It is not a matter of text messages. I sent a text message to my sister a few days ago. I don't know why. worrying .....
Today, I met my brother on the Internet and talked about how I felt when my sister sent me a text message. then he said this was what he told my sister. at that time, I was so angry that I believed him and told my master sister that he was always good. He would just pull me around and talk about it at home, let my mom know nothing. but he told my sister that it was either intentional or intentional !!!
He also told my sister that my sister may not be okay.
Sad ~~~~
My elder sister is the best sister in the world. She cares nothing about me, takes care of me, and even has never been better than her mother. how can I fail ??? If it hurts my sister's heart, I am really sad, and the culprit is the one who I think is a brother!
I will never forgive him!
I still hope that Allah can help me and don't let my lovely sister feel angry again. I feel uneasy. I am the responsible person.
At the beginning, my sister-in-law treated me well. I also hoped to have my personal concerns, so I recognized my sister-in-law. I didn't think much at the beginning, but today, if my sister does not forgive me ..... it's really sad.
He is no longer my brother !!!!!!
