Partner (M24) cheated and I (F24) threw all his stuff out

I am at a loss for what to do. My partner came clean that he cheated on me 2 weeks ago. It was with a coworker and it was a once incident that happened when they were at a conference. He swears that it didn't happen again but I'm not stupid and realize that they probably hooked up again after that. Anyway, I had thrown all of his stuff out and he's been staying with his brother since then. <br><br>We've talked a few times but I just don't want to be in a relationship with him anymore. He keeps begging to take him back and wants to work it out but I feel like he just wants me back because he has no place to go. He says that he's going to get his own place but it's not like he can afford that on top of paying rent for our place. <br><br>He wants me to give him a second chance because "he doesn't want to lose me" but I feel like I've already lost him. He has a week to get his shit together and move out before I start canceling all our shared shit.<br><br>What would be the best course of action?
