"History is repeating itself" sounds very passive. I think you and your former T can have some control over what happens and aren't fated to follow the same pattern as before. Since you have communicated with him recently to apologize, is there any way you could communicate with him again to tell him you need to be distant from him and see if he can help with this? If you tell him you may interpret routine pleasantries as "invitations" and are excited by them, maybe he can watch that more closely and give no smiles, no looks, no attention of any kind. He may want there to be no misunderstanding too, so may be willing to be quite helpful in this regard. I think therapists, in fact, often will not acknowledge current or past clients in public if the client wants it that way. Also, isn't there a health club you both belong to that you frequently see him at? Could you change clubs so this doesn't happen? If you feel unable to communicate with him to tell him these things, perhaps you could enlist the aid of your current therapist? If you give a release, your current T could talk to him and pass on this information.
