First tell him to fvck off and then block and delete him so that he can't send you bullsht mind game texts like the one he just sent you. You ended in bad terms. He broke your heart ~ why would you even consider talking to someone that did that to you?
If you're not over him after two years then you've not been doing the mental work YOU need to do to cleanse him from your head and heart. I suspect you've been comparing other men to him and have been entertaining your daydreaming thoughts about him and what little good he did bring your way while forgetting all the bad. Stop thinking about him by changing the subject of him when he pops into your mind and for goodness sakes ignore his text completely or, if you must tell him something, tell him to leave you the fk alone and then block and delete him.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
