My Ex-Husband Says We Made A Mistake?

There's no point in being prideful if you're interested, but that 's not to say you should rush into accepting the guy back. Who knows what his motivation might be. Be cautious. There's no reason why you can't go to dinner, feel it out, take it slow, and see what he has to say for himself. I think as long as you are not eager to fall for a line and if you can go about this casually and maintain a good distance, you should feel free to see what develops.
