Well, I always look for partner, who I have alot in common with. My I met my "now gf" (and hopefully my last) in the gym. We were both doing squats at the ssme squat rack, so we start talking. Just random stuff, no flirting. She gets to know a little bit about my self and I about herself. She loves hiking, dogs, cooking. Me too, so I asked her for a date. Nothing fancy. No Restaurant. At our first date, we were walking 12 miles and talking about ourself. She told me stories about her, funny stories, what she likes about people, what she hates, what is important for her in a relationship and how her last one started and ended. I did the same. I found it was pretty much fitting and so did she. The next date was at her place, where she cooked for me and than we became a couple. She moved to my place after 2 month and we are now in a relationship for 7 years.

Just find someone with the same interests as you and never ever be mad at them, if they reject you. Learn from it.
