You want to marry someone that you have to "summarize" information for b/c he can't maintain an "interest" in something that should be helpful to your relationship? Sounds like you are willing to do the heavy lifting in this relationship and that is not exactly a recipe for success. I recommend seeing a counselor about your different communication styles and the way you each handle conflict. I gar.un.tee you that any therapist worth his/her salt will tell you that saying the things your beloved has said to you in a conflict would not qualify as acceptable. ( I don't know what you have said, but you mentioned things he said in your post) Did you notice that not one poster recommend some books? It is not that they don't know anything to recommend, it is just that it would be a bit useless if he doesn't buy into it as well. Better off talking to a professional before marriage. Good Luck.
