I'm sure this has been brought up before but let's discuss the good stuff.
Some that come to mind
They have friends that they regularly spend time with.
They don't expect me to center my world around them and they don't center their world around me.
They can have calm conversations about things.
They don't adhere to strict old fashioned gender roles. I understand some people differ and prefer traditional.
They want to get to know me as a person. I'm not just a "cool" person to show off (I'm really not that cool anyway). I'm not just a body that they admire (nothing wrong with someone liking my body, but there has to be more).
They can pay their own bills.
They like cats and aren't allergic. (It's not their fault if they are allergic, but I have cats)
They have their own interests and respect that I have mine. I would add that we both should encourage each other to enjoy our interests/hobbies.
They are the type of person who has learned to look at themselves and take accountability when needed. It is something I learned how to do... Not perfectly, but I have learned that I have to face my flaws and own to to things. It helps me be a better person.
Genuinely a nice person, but not a pushover.
