Do you think this is considered cheating ?

[Been There]

It does not matter what I think is cheating. It does not matter what the next answerer thinks is cheating.
You are not in a relationship with me.
You are not in a relationship with the next answerer either.
You are in a relationship with your boyfriend.
The only thing that matters is what HE thinks is cheating.

You cannot keep a relationship if you keep secrets from your boyfriend. His best friend is not really his best friend, and perhaps your bf should know that.

However, if your bf is "every time" asking if you are cheating on him, this guy is screwed up bigtime, and the relationship isn't going to last anyway.
