My ex and I are more than friends but not dating, what are we?

My ex and I recently broke up and find that neither of us want to get back together (it simply won’t work). However, we still mean a great deal to each other and want to continue being close. For example, tonight he came over and we cuddled and talked and eventually kissed. And we both say that that is what we miss and want to stay like that but nothing more. I was wondering if there is a term or something for what we are then? And ideas on this in general…
