@Sannah, he found this picture and invite to lunch very provoking, I/my 18-yr old self was proposing a serious boundary violation.
I know I was VERY nervous about sharing it, almost had to hide this from myself.

Once he figured out what the picture was (Google street view not in focus), a look of horror flashed across his face. He asked "Did you take this picture?" He also wanted to know what was the purpose of the lunch invite, what would "she" expect to happen?. I told him "Wait and see, that's was the whole point, create the opportunity for something to happen".
When I was 18, this gave me great power, to get a 30-something man who should know better to meet an 18 yr old HS girl for lunch.

While later he acknowledged he knew I'd never show up, and I told him multiple times that my adult self would never and knew HE would never, I did pull out that picture at my last appt and tell him "It seems like sharing this may have caused you to withdraw, reset the boundaries" and he replied "I can see that" - no commitment either way.
