i read your message with great interest because i'm in A similar position. You played it well at the start but now you have to hold your nerve. Be friendly but distant. Be good fun but close down some of the areas of your life he once free to enter. Be unavailable at time and glue that happy smile on your face. Dress to kill and leave early to go to an appointment. Make him twist and wriggle. Slowly it will dawn on his dull male brain that being sinlge may mean that you may not care when he condescends to take you back.Let him chase you. it worked for my friend but she didn't want him then. good luck.
