Friendship broken?

So we keep in the laptop room and I showed a girl a photo. What looked like my best friend and his sister's mother. Who are not there at this time because they are sick. The girl of course told her mother and I got into trouble. So that my best friend said to me I'm ending the friendship. I'm not in the mood for you. I've messed up before and he gave me a 2 chance. And a few weeks have passed and we're now writing as if nothing had ever happened. And we also laugh at jokes together. And now I don't know if he still wants to be friends with me.

There are only a few people who can know that - to be precise, only one.

Which?

And?
