Hah, it's not even that. Things either fizzle or blow up before that conversation even happens. Or in the two instances, it's a no, and things blow up a couple of weeks later.
mhmmmm, I know that fizzle and I know that blow up. I also know I pushed away every guy who was a good fit because I got scared even though my brain came up with a bunch of not very important personality flaws to cover up my anxiety. It might be something different but it's worth evaluating your motivation a bit more. I could easily keep on thinking that I pick apart every good guy's personality because I actually found a bunch of things I don't like but I've realized I only do it because I'm afraid I will like it. Funny timing, I actually realized yesterday that my favourite bars are always dive bars but I fought it. I don't fight it anymore, I know who I am and I know what I like. I think every time we decide we like some thing we are putting a piece of ourselves out there. Every time we decide we like a person we are putting a pretty big chunk of ourselves out there. Are dive bars perfect ? Hell no, but they make me happy and that's what's really important.
