Friend Issues in need of opinion and or help.?

Well, first of all you need to talk to your friend who tried to steal the money and tell her that you can't really trust her if she does things like that. As for your other friend, you shouldn't get involved in how he thinks of the friend who tried to steal the money. If she steals from him you can say that you warned him and it's his own fault. And if he doesn't care that your friend tried to steal your money then he must not really care about your friendship because why would he take the side of someone who did something as low as stealing? That's just what I think.
