Hi Katie,
Break-ups are hard, by their very nature. It's impossible to say in advance how long it will take to get over a relationship and sometimes it takes much longer than one would like. I have been broken up with my ex for over a year and a half. While I am satisfied with my decision to leave him, I still miss the good parts of him, of our relationship. I think there will come a time for you too, when you are glad about the break up. It sounds like that time may already be here for you. I've found that getting over someone can ebb and flow; there can be unbelievably crappy days that seem like total regression, but, overall, it does get easier.
