Ex asked if I missed him?

(it was a LDR)We dated for like 6 -8 months and then he suddenly wouldn't answer me or text or call and so I took that as him breaking up with me so he texted me dec. 9th and I never answered him until now and he just asked if I missed him and I don't know what to say considering he kinda just left me without a word and I don't know how I feel other I am angry at him and right now I am not looking for a relationship I am focusing on school and working!
