you make no sense
If your sister goes with your brother then it's incest and they would both be your siblings. If a girl is dating your brother and they get married this would make her your sister-in-law.
Maybe she would learn to behave next time.
go up to her and ask her why is she ignoring you that she is being selfish and you dont like it,you miss your sister
No.
It is your sister's or brother's son, your adopted sister's or brother's son or your half sister's or brother's son. That would make you an aunt or uncle.
Your sister-in-law is either the wife of your brother or the sister of your spouse. Your brother-in-law is either the husband of your sister or the brother of your spouse. So your brother-in-law's wife is either your sister or is not related to you. Some people incorrectly refer to a brother-in-law's wife as a sister-in-law.
he did have brother and sister he had two sister and he had 1 brother
There are two ways that your husband can have a brother-in-law. In neither case is his brother-in-law also your brother-in-law.Your husband's brother-in-law may be your brother.Your husband's brother-in-law may also be the husband of his sister. In that case he is the husband of yoursister-in-law, but that does not make him yourbrother-in-law.
