So instead of the No Contact-rule (of which I wasn't really aware, I am hardly a break-up expert) I told him straightforward that I wanted to sort things out and try to get back together because I felt I made a mistake. He feels it's the right decision for us to break up because of all we have been through. He doesn't feel we can ever work that out and have a chance of successfully getting back together. So he's actively moving on but wants to stay friends as we might continue to see each other occasionally. However: one day he tells me he doesn't WANT to work things out and has no feelings for me whatsoever and the next he claims that he DOES want to work things out but just feels it would be in vain anyway seeing the arguments and fights we can't seem to work out (I feel we can work them out). Right now I'm aware that he really doesn't want to get back together, I know him well enough to know what if he's into me, he'll let me know. I have never ever had to guess how he felt about me.
However, I do think that time heals all wounds. I know what I could and should have done better. I don't want to make this into a stalking, stage5 clinger project, but I could see us ending up back together in the (near) future because we did have real chemistry. He's not ignoring me and we still talk every now and then, though I told him a couple of days ago I needed some space and time to heal.
I don't know how to handle this very uncertain situation: should I remain a friendly, but somewhat distant contact and build up some trust again leading to possibly a new relationship? Or should I keep my distance and 'let him be', even though I feel we have the same goals in life?
