**HELP** Where can I find a girlfriend other than these places?

So, I'm in 8th grade but hang out with mainly 9th graders. I don't like any of the girls in my grade at my school or other schools in my area. (I'm bigger than everyone in my grade so the older girls think I'm cool) I've only had relationships with older girls this year, but they have all been ended mutually. The first one lasted a long time but I didn't feel anything in it. The second one was very physical but it never really took off cuz she goes to a different school (we made out, and got to third base, but we stopped texting, hanging out, and just talking but I still kinda like her. I thought she liked me but she doesn't tell me anything that happens in her life so I can't tell what she does half the time) I don't know what to do. I don't know where I can find a girlfriend that I can see a lot, and hang out with that won't go behind my back, and will be pretty physical but not sex. What can I do to find girls? Help please?
