Talking to ex about our feelings for each other?

So, my ex has been sending(what I think) are signals he regrets breaking up, or that he at least has feelings for me again. My friends all say I should talk to him so I can know one way or another. I know they’re right, but I’m terrified of confrontation. So I’m sitting here hoping he’s braver than me and will bring it up first 😂😂 any advice on how to approach the conversation? Should I do it through text? Or just tell him we need to talk, then sit down and hash things out? Or just say fuck it and wait for him to do something about it?
