Thanks everyone for your replies, just a follow up to confirm you were all right :)

I did meet this man again some time ago, roughly one month after the break up and with NC. The good thing was to see there was still a connection between us, both care a lot for each other and enjoy each other's company, very pleasant meeting overall.

But I have to say that you were all somehow right. Though during the meeting I felt perfectly comfortable with the new state of out relationship, it is a way of holding on. He was slightly enigmatic and more flirty than I would expect and I couldn't help wondering about what'll happen next and whether at some point things could work out for us. On my side I was much more comfortable and prepared for no romantic element at all. I guess it's normal given he was the last person I was intimate and emotionally close to but I think I should be careful and not get too worked up with this. Or maybe it is just a transition and it'll take time for his and my feelings to calm down and that flirty component to go away. Still not able to talk openly to each other about what's going on also, not to even to ackonoledge that's a new beginning and the rest is mere past.

I keep reminding myself though I should focus on myself rather than others and spend some time on my own to know what I want and that I can be happy and whole on my own for the first time in years... And that I should be ready to let this go if it provokes too much pressure on me and holds me back
