'...i'm pretty sure he won't get nasty, but just a little bit apprehensive. Its early days yet, so i don't doubt he's calm, but he could decide to turn just because i've taken control...'
I doubt he (or indeed any man) would put that level of thought in to 'turning,' it's just not the way they think. You might not want harsh comments but it's kind of hard to shake sense in to you through a screen. All the above are your comments, your thoughts and they're the same comments and thoughts you've had for a while now. Your mind is on a loop that you need to break, as I said before, it seems to me YOU'RE winding yourself up way more than he is.
You need to find something else to focus on other than your continued suffering over this chap... Feeling sad a relationship has ended is one thing, constantly winding yourself up so you're always on edge and over analysing everything you're doing is really quite another set of problems.
I don't think your posts looking for reassurance are helping you, I think they're feeding in to your mindset. Perhaps just joining in the general chat on CB would be more benneficial to you in the long run.
