Not feeling the effects

I'm not sure if I quite understand it myself. I have been browsing here for a while and have totally gotten that I should let it out, feel the pain, have a good cry........ I had been on and off with N for 7 years then in the 8th year, married him on March 23,2013. I could never have imagined the hell I would live this past year. I'm still not even prepared to discuss it fully. It was just bad. I left on April 30th, and to this day, haven't looked back, cried, or anything emotional. I just moved on. I get up and go to work everyday....sometimes with a bounce in my step. I closed accounts on the day I moved, changed passwords, moved where he wouldn't find me- I even park my car away from work so he won't come in. I don't even know if he has driven by. I do know that 3 weeks into leaving, he has stopped by my mothers house to tell her what is wrong with me, has texted very lengthy messages to my friends and on mothers days, sent my daughters flowers and cards. I still remain cold to any of it. Indifferent. I cried all the time when I was there. He did terrible unthinkable things to 'us', while I was there. I left without a clue. I'm just wondering............. should I be crying? Whats wrong with me that I am not crying? I am seeing a wonderful therapist. I started when living with him. I really have quite the education on Ns and so I'm wondering...........do I even need to cry. Will I be ok if I don't?
