Loleta,

There are strategies to separate yourself from him as you well know.

Block him on your phone and social media (or delete him).

Do not respond if he does reach you.  This can be a mindfulness exercise when he does reach out to you, you can pause, breath, and decide not to respond.

Focus on nurturing yourself, i.e., be active, be social with others, meditate, exercise.

Frankly I think it is a you are not valuing yourself enough to give him up.

I believe a good therapist does not tell you what you need to do but help you become healthy within yourself plus have tools to use to practice good mental health.
