Hi Robbity. Rare for someone to post after they were the one to leave. I'm far from an expert , so please take my post accordingly. IMHO you left this man and while it appears he still has feelings for you , I'm sure his ego is very much on the defensive

From my own experience , whenever my WAW / WW would even remotely bring up any talk of an R , my ego would jump in to ' protect ' me Maybe this is what's happening with your XH ? Wounds take time to heal and even if your XH didn't seem hurt at the time , I would imagine you asking to separate would have hurt him quite badly

Maybe take time if you want to begin a new R and let XH come forward in his own time. Just my humble opinion

Take care. Rd
