That is pretty much what I have done with my daughter. Just cut it off!! There are always people who will not or cannot understand you, but sometimes we have to take care of ourselves. Others just see that sweet person who they don't know is getting ready to take advantage of them and use them for all they are worth! My daughter had only one friend, a Mennonite lady, who she has used to death. Now, this lady is catching on, and my daughter will find someone else to use, then disgard.
