Advice on meeting then

Okay so, I would like some advice because I have mixed feelings on it.

My ex broke up with me in April and now they told me if I ever need to have the conversation personally to let them know, but from their part it's solved.

I don't know if I need the conversation but I'm quite unsure if I want the last time we saw each other to be the last time, since it was my birthday.

I don't know if I should try to have the conversation but at the same time..what's the point..they are completely disconnected from me.

I genuinely feel like I don't know this person, because it wasn't the one I dated.
