Thanks Rhapsody!
Nothing inappropriate has ever happened between the two and this pdoc is VERY strict with boundaries even for members of his forum. They've just had dinner three times (not alone, with other members) and went to some museums and stuff together (again not alone, with other members).
This pdoc isn't even friends with his members. They just get together once a year in celebration of the forum's birthday.
I was thinking that the crushing on your pdoc thing happens all the time and this is kind of similar so, it's probably OK.
