Crazy story

So my bf has this friend that was dating this girl who is literally using him for his money. She doesn’t have a job yet lives in a 1000 dollar apartment and has a kid too. So I’m like how did she even get that place anyway. She told him that the landlord wanted her to screw him for making up the rent which I think she is doing it anyway. None of the things about her is making any sense. She is always demanding for my bf friend to send her money or if he doesn’t then she gets all sort of pissed off about it. Her friend texted him out of nowhere saying for him to pay her off and dump her. Also the friend is wanting him to date her instead of her friend since she treats him poorly. What kind of friend does this anyway. So he ask my bf and I what he should do? He wants someone he can settle down with but first I think he needs to say goodbye to being a little man whore then settle down. He was going to marry the first girl after three freaking weeks of knowing her. My bf and I are almost a year and aren’t even engaged yet lol so he is in all kinds of weird stuff. Apparently now he’s talking to the ex best friend now so I can see that starting so much trouble. Please pray he makes wise decisions.
