That sounds frightening. I hope that however you decide to carry, you have sufficient training and LOTS of practice drawing and shooting from your holster in case you ever need it.
Now, back to the question... I also do both CC and OC. It really depends on where I am going and how I am dressed.
First let me tell you what I tell my students, and that is that even if OC is legal, it is not always prudent. First of all, if you happen to be present when a bad guy decides he is going to rob an establishment, you have lost your element of surprise, and you will most likely be the first target.
Second, in the county where I live, most people are very accepting of guns, but if I go into the city (like Aurora where the theater shooting was) there are too many soccer moms afraid of guns, and an unfortunate part of our gun culture is that we are guilty until proven innocent. I don't want to have to be subjected to that. So, with that being said, I OC in the country, and CC in the city MOST of the time.
If you don't already, I would also recommend that you keep a gun at the ready in your home. You are probably as much, if not more at risk there than anywhere else, and since you have someone who has it out for you, he could probably figure out where you live fairly easy.
Stay safe and keep us posted.
