If it was before you began your relaationship, no. There's no point and it's completely irrelevant in any case.
If it was after beginning your relationship, you might want to tell him. He hears it from you first and you don't start a habit of cheating on him.
You should do whatever you think is right. Although honesty is the best answer (and believe me, i know) you shouldn't let people talk you into something your uncomfortable with. If your nervous about telling him, wait a while until you are ready.
the one night stand cuz your body isn't used to that guy so it took it faster

She has her reasons - ask her. But most likely because she didn't want it because she was your one night stand and not a serious boyfriend or husband.
Let her go and find someone else.

They start for at least a month.
boyfriend
If he doesn't know, tell him. If he knows, ask him how he feels about it. I had a one night stand with my boyfriend's brother long before I knew my boyfriend. One night when we were just dating I told him: I have to tell you something, it's about your brother. He answered: If you are talking about the one night stand I already knew. Than I asked: And are you OK with that? He answered: Do you really think that I would date you if I wasn't OK with that. Than he he laughed and kissed me. We have been together now for 4 years :)
0, Zero. it's your boyfriends.
