Step uncle
She's just another person in your life. She has no relationship to you as far as family lineage, not even by marriage. Your stepfather, also, doesn't really have any relationship to you except by marriage.
There is no relationship, they share no common ancestor.
There is no actual relationship between the two of you. Anything could happen. At 13 I wouldn't worry about it.
no there not his real dads name is Jeremy bieber, his step dads name isn't Jeremy
Yes you are family. You are step brothers or sisters.
I think if a step brother and step sister want to be married it is fine. I have known people who have done this and they are still very happily married after over 30 years.That is kind of weird. I guess it is okay but is it still weird?Added Answer:There is no legal impediment to a step brother and step sister marrying, because there is no blood relationship between the two. For this reason it would not be considered a legally prohibited incestuous relationship.
In most families he would be called your nephew. But there is no real relationship. Unless your brother adopts him, which would legally make him your nephew.

If your step-brother has the genes from one of the parents and he is telling you romantically he loves you and you had a relationship it would be considered incest. If your step-brother is not genetically related to you and you both love each other then it is possible to love each other. If you do not love him tell him honestly you do not, but love him as a friend.
