The facts you describe above contain nothing that makes me suspect unlawful discrimination. You do not indicate a refusal to hire you on the basis of race, gender, national origin, religion, color, or other impermissible classification. So I see no basis for a claim of discrimination in employment. It's perfectly lawful to refuse to hire someone on the basis of most reasons other than these.
Not legal advice as I don't practice law in Kentucky. If you need legal advice, please consult a lawyer who holds Kentucky licensure.
Good luck in your job search.
I agree with my colleague. Even if the DM is making it personal and discriminating against you, there is no illegal discrimination. This is not because of race. sex, age, religion, etc. It may be because you left and DM felt betrayed. That is not a cause to sue.
