BLUF: was in a relationship for 2 years. Ended this past August. Radio silence with no plans to break that since. Ex has attempted contact via text a couple times after that but I blocked the number around November. So no knowing how much I missed until now. Sends me a facebook message (not friends on facebook) about feeling bad about how things ended and wanting to talk about it because she didn't like ending on a bitter note. (Yeah ok). Do I just keep blocking her after every new media contact? Or do I break radio silence simply to tell her to stop contact.

Side note: I made it clear during the relationship that I never speak to exes. I don't want breaking radio silence to be an indication of going back on my word, and in turn her thinking I'm receptive to meeting for any reason.
