What’s the best thing to do in this situation?

So my friend who lives a couple states over is down at the moment and has been for the past couple weeks. She lost a friend that she thought would never do her wrong or talk bad about her and she was. And then the guy who knows the friend was talking to my friend and whole time was doing stuff with other girls while talking about getting a place together. I like the friend because we’ve been talking a lot basically everyday for past 3 weeks all day. I care about her a lot and she knows but I don’t want to do too much like overwhelming you know. My first instinct is get her whatever she wants and help out to my highest extent. But I don’t want to go broke trying to help and I don’t want to overdo myself.
