Should I tell the guy I'm seeing that I cried over my ex today?

it's been a year since we broke up but he had traits that I have always wanted in a guy but suddenly he ghosted me. to this day, I think of him like maybe 1~5 times a month. but the guy I'm seeing, I told him I'm not ready for a relationship so we just stayed friends but we like each other. and I'm curious if I should tell him about me still missing my ex?
