What do you look for in a relationship?

Hey y'all. Quick question about opinion. What do you look for in a relationship? Me personally I look for someone who completely understands the sh*t I go through, and who actually gets it. I am an only child, and not very many people understand the kind of crap I go through. Sometimes even *I* don't understand myself. I get lonely very often, and my subconscious and imagination play with each other and sometimes my imagination plays rough. There are some things that my imagination does with my subconscious that is sometimes not even possible to put into words or a description. This is why I look for a relationship. Not for doing the dirty, even though most people think that's what a relationship is about. No, my reason for wanting a relationship is someone to spend time with and have complete understanding of what I go through. I'm almost 21 and I never had a real relationship before. The "relationship" I had in high school was a trick. But I want that 21-year streak to stop. NOW.
