It seems as if everything you are thinking about and expressing is aimed at determining if either or both of you are appropriate for this relationship or committment. I believe it should be looked at the other way around. You both bring things to the table when it comes to discovering if you enjoy each other's company and are compatible. If being together brings happiness and joy then that joy usually compells a couple to take it to the next step. They go to that next step knowing that the first step worked so well. You seem,however, like you have taken it to the next step before you are sure that you are both experiencing compatibility. That is not to say that it should come without a few complications. Life is not always a bowl of cherries. Any relationship has it's ups and downs. It sounds like he expects things to go perfectly and has a preconcieved notion of how love should be. From some of your questions, it sounds like you are not sure what to expect or you wouldn't be asking. His expectations of perfection will change by knowing more people and your questions will be answered in the same manner. How else do we find out if not by comparison. In any case, dateing until you both come to the point where you are ready for the second step seems like the way to go. He has expressed the happiness he feels but has he enquired about yours? It seems like you are overly concerned and analyzing your compatibility for the simple reason that you have the pressure of premature expectations from him and yourself being put on the relationship. Perhaps it might be revealing to ask yourself the question: "If those expectations were not there, would I be able to relax and just enjoy the relationship and not keep questioning it?" The progression of a relationship should be a mutual agreement. It is hard to express that to someone when they seem head over heals and are already nameing your children. If you are self analyzing and trying to fit into the picture he is creating of your future together, then you may be doing this the rest of your life. It is also your life, and you should feel ready for it and be a part of how it unfolds. One thing that you have worried about is the possesiveness. It is a fine line between overwhelming love for a person and unatural controlling posessiveness. If you choose to slow down the relationship and date for a while, you will certainly come to know which one is the case here.
