Dr.Jekyl/Mr Hyde

Don't want to admit this, and of course,it makes me feel ridiculous and stupid..met this guy 5 months ago,and he came across as a really genuine sincere person.Everytime though going back to his place came up, he always had a ready excuse.And he told me he was just way too busy and travelling way too much..well. We ended up going to his office a few times.Till eventually thats all we ever did.When I got curious,he put a swift end to my questions with talk like,"don't mess with me,am not a nice guy when angered".This from somebody who is a professor!Now I find that the office we frequented,is one of the many,he is a consultant or some such with this one.Am sure now he has a wife or partner stashed somewhere safely.And I have been plain dumb.It angers me of course,problem:there are photos he has of me!And since his transformatiom from Mr Nice to Mr.Rat..am nervous knowing he has these.Any ideas anyone? Or should I just walk away and hope to hell these photos never surface!

Thanks Chiki,this thread also on Marriage & Relationships, and have been going through thenightmare there.If you read there you will know its progressed.Although...what you said...I really really should have done that before I decided to leave!So many what ifs exist now..Thanks again.
