I think my friend might be a lesbian? Should I talk to her?

Maybe Nicole is a lesbian and maybe shes not. Since Its an abusive relationship between the 2 she is probably forced into it and cant get out. You should take to her. Even if she gets really mad at you, shouldn't her safety mean more though? Talk to her. Tell her that your there for her no matter what and she can tell you anything. She doesnt have to take it. She is probably being forced into it probably because its the bully who shes with and she might be getting forced and/or threatened.
