So there is this new girl at work and i've just became friends with her last month. But there's something weird going one. For the past few weeks when ever she comes to work she has these bruises on her arms and when ever i ask her about it she'll pull her sweater down and make up a excuse like she fell or hit the door. And the other day we where late getting out and her dad was picking her up and she just looked at me and it was kind of a scared look, but her dad looked even scarier like a abusive type. So I'm scared that she's getting physically beat at home, and i want to help her i just don't know what to do. I'm scared that if i ask her and that's not the case she'll get offended or if it is the case she'll deny it and never talk to me again.
What should i do?
