It sounds to me like you both have some unresolved business. Did you both break up officially or did you just stop speaking with each other?

I think maybe a few days without a reply would be an indication that he doesn't want to talk... Is your reason for wanting to meet up just to discuss what happened between you two? Do you want to get back together with him?

So update!!

We ran into each other this weekend, randomly, After trying to be charming as if that still works on me  , I asked him  why hadn't responded and he stated that he didn't want any drama.

So, I asked him why would there be drama and he said,usually I end up yelling at him and he is triggered and that's why he disappeared.

In turn, I asked him did he anticipate a reason for me to yell? And I told him I don't like to yell and that it is usually out of frustration. He basically apologized for disappearing because he knows it isn't right.

So then he asked me what is it that I wanted to talk about and told him a lot because there is a lot.

So he is supposed to "set up or figure out when" and let me know.
