I thank you greatly for your educated opinion on my matter. As I said before, I don't feel the need to defend me relationship on the internet, but your posts are not an "attack", so I thought I'd reply in kind.
I'm well aware that there is a lot of hardship coming up in this relationship. I also know that though she is young, she has more potential than any other girl I've met throughout my years. It's not that I haven't been looking, but I have a general disgust by how men and women act, especially in how they attract one another. But I won't go on, because this isn't meant to be a ranting post.
The most important thing I should mention about this relationship is that I'm not in it for sex. I've never been a very sexual guy, and am still a virgin who has very normal masturbatory habits that don't need to be elaborated on in this board. I've never gotten involved with anyone because I was not attracted to them. It's not that I like this girl because she's 15. Her age is quite an inconvenience for me, in fact. I would have loved to have found someone so smart who was also past the age of consent in my state.
At the least, your story has given me some hope. I cannot promise to follow through on all your bullet points, but would like to mention that many of them were already in my plans to begin with. It's all a matter of getting her mother to accept me on a basic level so I can get her to open up further. I would have done this if her English comprehension wasn't so lacking. It's there, but as I like to use "big words", I'm afraid they won't be understood that well.
In any case, thank you for your story and advice.
