Someone I care about keeps asking me to send money but he needs to be cut off. I'm trying to have a serious talk with him about it. Advice needed

This is a post I put on Chambers in another sub. I know online strangers can't help me, but writing it down and reading it back to myself helps.<br><br><br>I am currently in a really tough situation. (30s M) I have learned that a close friend (40s male) has been asking another close friend of mine (20s F) for money and getting money from an old flame of his (40s F). I wasn't aware of any of this until the other day and he's also been asking me for a lot of money over the last 6 months and I have helped him several times. <br><br>I'm exhausted and feel like I've been taken advantage of. I've been helping him by sending him money, but it's at the expense of myself and my family. I can't keep doing this. I am going to have to have a serious conversation with him and set a boundary. I'm worried because I have an idea how burned out I am and how much I've sacrificed, and now I have to learn that he's been asking everyone for money? And he's been lying about it? He is going to get mad at me when I bring it up. <br><br>I've offered to let him live with me but he says no. I've tried to set boundaries and he gets upset. <br><br><br>I think it's a little too late for an intervention. I want to continue being a friend to him, but I can't keep doing this. How can I have this conversation with him without it getting out of hand? What if he gets mad? I have tried to have the conversation before to no avail. I need advice on how to get this conversation to actually happen. What can I do?
