Like for me, I have high expectations because I had guys who treated me wrong. They would take advantage of who I am, my emotions, and have no problem with that. Last guy I thought I had the option to date... he threw me under the bus, lied to my parents, blamed me for the whole thing, and didn't believe me about my disabilities plus he wanted me for how I look.
I try to think I like to go with the flow, but I've also got some strong standards when it comes to dating. I highly value communication, and although I can be quite extroverted, I have to make it clear to my partner that I need some alone down-time every once in a while. Just gotta reset my social battery.
It goes both ways for me though. I can work with my partner and talk to them about how I'm feeling, as long as they can do the same for me too.
