It's best to leave the past in the past and only bad things can come from being back around someone who is toxic to you. It would be like getting over a drug addiction but hanging around the people who still do it. Eventually you get pulled back in.

You say you don't have intentions of getting back with him, but he's an ex that you still have feelings for, not just some old friend. You probably do still like him deep down. And you say you know you should've broken up so you prob shouldn't get back with him
