You have received a lot of great advice here. It really is way too early for your W to accept any responsibility. I have been at this longer and I am still waiting. Mine has only gone so far as to say she is messed up. While they may not be accepting responsibility right now, that does not mean they won't accept responsibility in the future. (I believe that will be an important first step to reconciling.) I can also add that my IC says it is up to me how long I am willing to wait. He would not recommended waiting indefinitely, but he also wouldn't put a date on it.
Some of your contact does seem like pursuing. At this early stage, I can tell you it will probably be unwelcomed. Your W's response (if any), is only likely to disappoint. We all want to believe that our situation/spouse is different, but we just end up learning the hard way that there is a pattern and that nothing will change or be fixed quickly. Generally speaking (although there are no absolutes), I wouldn't call unless called (and then not right away); don't email unless she emails first; don't always be available; don't try to extend conversations; and avoid being the last person to respond.
FYI, it is best to avoid descriptions that include always and never. Life is full of exceptions, and you can probably name a few.
