I have trust issues. I also have trouble remembering that I told someone to do something if they do it and it turns out I didn't want them to. Therefore, I'd probably break up with him. Unless he has me on tape saying "push me if I back out, but don't tell me you're going to."
I am afraid of heights. I know that every time I have ever been in a situation where someone who knows about my fear of heights decided to use it to get a few laughs at me, my fear has gotten worse. In order to get over my fear of heights, what I need is someone who will challenge me to face it, but then hold my hand while I do, and hug me afterwards, and during the experience do everything in their power to make it a good experience. And I need 3 good experiences for every 1 bad experience with heights... so right now, I'm up to a good 21 experiences (give or take a few). Yeah, people are dicks.
"You have to face it to get over it!" is their excuse, while they do something to make the fear even worse...
