First off - just want to encourage you to take the obvious necessary steps that you yourself outlined.... Keep moving forward. This person is obviously not seriously interested in helping themselves. He sounds like a horribly itchy, clingy, foul-smelling sweater on a nice spring day. Ditch it.
Second off - hope to encourage you to stop saying and thinking that your reluctance to have even the most rudimentary boundaries is a matter of you not being ABLE to do so. I have made some very profound changes in my life by simply shifting my thinking from "I CAN'T" to "I am choosing not to." It's just more honest. And, at least for me, it encourages me to think through the excuses and roadblocks I am putting in my way.
Thirdly - You do an admirable job at finding the humor in it all.
