Trying to Decide if I Should Get a Divorce or Not

My wife and I have been separated for a few months now. I thought that being separated would make me miss her and wish that we were back together. However, that has not happened. I am wondering can I save my marriage and do I really want to. I feel happier being alone right now. However, I wonder if in time that will change. I am going to try to talk to my wife about it to see how she is feeling about all of this. I would like to see if we can get on the same page and then move forward.
