I really really don't like the OlD scene, its just filled with predatory, egocentric types it seems to me...its so easy for people to be cruel and heartless...I avoid it like the plague.
I won't be dating for a while, and certainly not online dating, I'll take my chances with real life possibilities when the time is right, being able to get all the cues and intuitive clues that we get from face to face contact is essential to a healthy start...not to mention all the people on there who get rewarded for the WORST behavior.
I sympathize with that feeling of insecurity you have about that vulnerability you risk by putting up your picture and details about yourself.
I'm really sorry that a-holes gave you such a pile of crap.
I am sure you don't deserve it at all...my impression from your posts is that you have a really awesome sense of humor, and wit, you have great intellegence and reasoning ability, and look at you, finishing school like you are is going to get you far in life.
