what would you do if you were me?

So me and my ex broke up a couple weeks ago but still talk on a daily basis and are still sleeping together (friends with benefits) I had been messaging this new guy for just over a week and he's super super keen, but he doesn't wanna continue talking if I'm sleeping with my ex but I just feel like I need my single time at the moment , idk what's best ? Shall I keep sleeping with my ex? Sleep with this new guy? Idk 🤔
