As far as you doing all that stuff for him, yeah, it's pursuing. He is getting the best of both worlds. Holding Divorce over your head while doing things together is really IMO wrong.
My W moved into her Sister/Boyfriend/whatever house, so I don't have the experience of what you're going through. I hate the fact that she left, but at least she made the decision to leave and not sit here to force me to endure a relationship that is fated by her "I'm not changing my mind" speech.
I'm at my wits end with dealing with the whole detach thing. I broke down and got a DB coach (starts Friday, YAY)
I would advise the same to you, but if you don't want too or can't, just focus on doing things for you and not him. He wants to treat you that way then let him go.
There are plenty of people with better experience in handling this and they will offer you better advice, so keep checking back.
My heart goes out to you and I hope everything gets better for you.
