Ran into Ex that dumped me a few weeks ago and he said I could reach out to talk anytime. Is it bad that I want to?

He dumped me in a really horrible and confusing way, I won’t get into but it was very bad and re traumatizing for me. I was mad ofc but I thought we may stay friends in some capacity, especially because he made it clear he wanted to stay friends, ultimately he ghosted me and really never responded to any of my texts seeking answers so I ended up blocking him on everything in July.

Ran into him a few weeks ago, he apologized for what he did wrong and said If I ever wanted to reach out to chat I could. I didn’t care at the time but now I really want to say hi. I don’t have any intentions of trying to get him back. I’m just curious about how he’s doing. I also kinda want some answers but I doubt I’d get that from him.

I just feel like if I do he won’t reply again and I’ll just be disappointed all over again. I feel like it’s not worth it but he also said I could. Idk if I should believe him. I don’t trust him.
