Well keep track of these things in a journal. Also keep track of what you were doing that way you can go back and see what worked and what didn't. It's good he's starting to show signs of caring. BUT I want to give you a heads up, my H would "care" and show signs the man I love was still in there, then he would pull back in a big way and go back to the weirdo jerk I couldn't stand. So if that happens here, do NOT be discouraged. I think the reaction the pull back is "What the he!!? Why did I act like cared? OMG??? Do I still care?? Holy crap!! No, I don't care and I'll show her!!!" That's what I always imagined went through his head once I finally caught on to what was happening, the pattern that many of our fellow veteran DBers warned me about.
So, like my coach said, enjoy the positive interaction, but you can't act sad or upset if/when he pulls back. Just maintain the cool calm sexy you and let him figure it out.
