OP here.

It's pretty depressing to me that people are so negative about this issue. I'm sure you all are basing your recommendations / revulsions on previous 15 year olds and 20 year olds who might come to like 15 year olds that you've known. I won't bother convincing anyone that the two of us are different since I'm sure that's what everyone says, regardless of the truth of the situation.

Since I came here for legal advice for the most part, I will continue being sincerely attracted to this girl, we will continue loving each other for quite some time, and judgmental people on the internet and in real life will just have to deal with that. While it doesn't deal with the same specific age difference, I recommend people watch an excellent movie from 1971 called "Harold and Maude" for more education on age differences and love.

Feel free to talk more about this if you guys want, but I feel no need to defend her or myself on the internet :V
