Still feel I need to lay some things out for him - about me working on myself and giving him space. While I don't think I need to lay out my plans for him all of the time, I don't want him to think I am dating and that it is ok for him to at all.
I don't think you should have to explain yourself in too much detail - you still want to remain mysterious to make HIM think about what's going on.
There's nothing wrong with setting boundaries - they are very important. You are both still married and unless you have both agreed that it's okay to date other people, it needs to be explained to him in that manner - but keep it nice and civil, regardless of how he reacts.
At one point my W accused me of seeing someone even though there was no way possible I could have (every hour of my day was occupied). I flat told her I was not seeing anyone, but, if she chose to believe that I was, it was totally on her to do so. Dealing with a WAS is no fun - it almost caused me to walk away several times. So I definitely feel for you and your sitch.
