Maybe he lost your email address. This can happen.
Why do you think he has stopped writing to me?
How should I know why he has stopped writing to you?
I am sure the girl is the reason why.
There could be other reasons why he does not write.
Like what for example?
Maybe your brother is angry with you for some reason.
That is no reason. At least it is not a good reason.
There could be many different reasons why he does not write to you.
Why do you say that there are many reasons?
I am just trying to help. You need not worry about him.
