Hey Kassie, good job on setting some boundaries. He can't be doing that stuff while you're at work. Sheesh.
I think he's realizing how dependent he is on you, & he's afraid of not having you around. I could be wrong, & have been numerous times, but it sounds like he's trying to intimidate you into coming back. That's not a real effective way to woo someone. ya know.
If he's recognizing and admitting that you're pushing him away, he really needs to look at what he's contributing to the experience.
take care
