A few years is pretty vague... are we talking 1 or 2, or 3 or 4? And I hate to break it to you, but if she is over 18, her being with you carries criminal penalties. These penalties exist because there IS a huge gap between the maturity levels of children and adults and children can be easily swayed to do things they might not otherwise do.

Honestly, I say forget about it. Aren't there any cute 15-16 year old girls at your high school?? And really, if you are thinking about "spending the rest of your life" with someone at the age of 16, you need to be smacked upside the head. Especially someone from the interwebz that you have never even met! Be friends with this person. And that's all.

My other, unsolicited, advice to you. Get out! Get out from in front of the computer and go do things outside in the real world! There are girls there you can talk to and look at!!!
