Glad to see you picked up those books. I would recommend reading them in that order and also picking up the Passion Trap if you have not read it already (I did not read Solo Partner as some reviews I read indicated it seemed more geared toward a slightly older generation than ours but I believe the Passion Trap covers much of the same pursuer-distancer dynamic discussion).
As for handling situations in the future - sometimes the best thing you can do if you don't know what to do is do nothing. If he asks you a question, you can tell him you'll get back to him on it because you need to think about it. Etc. Don't feel pressured to act on everything in the moment.
