My ex of 3 years and I broke up almost two months ago..and now he's playing mind games with me?

Take your time to find someone. Let him move to Fl. if you had problems in the relationship before what make you think there still won't be problems. Let him go. What right does he have to ask you personal questions? If you fall into his trap you'll be stuck again. Look he started dating 2 days after the break-up what does that tell you. Listen to your heart, before you hear whatever anyone else has to say.
