A few cents....
She's clearly frustrated with OLD and the quality of men that she is meeting. Believe it or not, OLD is a scum bucket when you are looking for men, as well. I'm not saying that there are not god men on OLD, but, sh1t, they are hard to find!
You got a little overly sensitive when you interpreted what she was saying and responded "so meeting me is a waste of time?" If some dud responded to me like that my immediate thought would be that he must lack self esteem to be asking such a question. You can think it, but never express things like that. What you express is "You seem frustrated with OLD, I can assure you, you wont find me a waste of your time".
She's screening
because, as she said, she's shown up on dates before where the men have lied (im sure y'all know what that is like) she's tired of looking and smelling nice, and taking time out of her day, for a man who has lied to her about who he is, or what he is looking for. She has decided that she is going to be upfront with her OLD prospects. She is a little harsh, and blunt, about it, but it seems like she figures every guy is probably lying/not a good prospect, so why not be straight forward.
In all honestly, she should probably take a break from OLD until she has better perspective. OLD is a place you walk into believing you will be let down. that way when the date is not bad, you are surprised.
@XI AlphaMale IX YOU didn't do or say anything wrong in this exchange (outside of appearing insecure with that one comment) In this case your best angle would have been to realize she is frustrated and hit up the sympathetic angle (I think
@El Payaso or
@Bible_Belt belt talks about this well) The angle of empathizing..... "Kim, I can see you are frustrated with the quality of men you are meeting on OLD. I completely understand where you are coming from and, to be blunt, I am relieved that i am finally talking to an OLD female that has standards and screens her dates! No, I dont smoke. No, I dont want children. We should definitely meet up for a drink, how about X day at Y time at Z bar? At the very least we can have a few drinks and swap horror stories"
Or something along those lines. Im sure the guys will correct me if I get it wrong somewhere......
