What did he mean by saying that?

so i dated this guy for 6 months and now we been broken up for about 3 months and lately he has been constantly stalking my socials and i texted him asking what is he trying to say by that constant stalking and he said it just a coincidence and said i will never forget you but i dont miss you so im wondering what did he mean by saying that cause his actions and words dont match up

What did he mean by saying that?
