So there's this girl...

[MajorTom777]

I'm a guy, a junior in college, and I'm currently single. About a year ago, my younger sister's best friend told me she's had a huge crush on me for a while. Now she's a senior in high school and that's not a problem for either of us, but since I'm away at college I kind of told her I wanted to wait until the summer after she graduated. The reason I did this was because I realized, yes I want to date her now but then she'd miss out on some things her senior year, like going to prom with someone she liked or whatever. So we agreed we'd hold off on it until then. I'll also add that before she told me, I had never really met her so I wasn't having a hard time with the wait. About 3 months later she was asked to junior prom and started going out with this guy at her school. Now they've been "dating" for a while but she's said it's not serious. I have to tell you it still didn't bother me at all. We still hung out and everything was fine...
Until a few days ago. Now before I continue, at this point we've gotten really close on a personal level to the point that I loved her as I could love a family member but not any more because I knew I couldn't do anything since she had a boyfriend. It was her birthday and after she had done her whole celebrating thing, she and my sister came to hang out at my house. I found it odd that she wasn't with her boyfriend but whatever. So we were all watching movies and I was sitting next to her on our couch. She eventually leaned her head on my shoulder and started holding my hand. Then rubbing my arm and running her hands through my hair. Now I'm still thinking "she's just flirting, nbd." After cuddling up for about a half an hour she looked over my shoulder and once she saw my sister was asleep she slowly put my hands on her boobs. I was really surprised by this but admittedly happy because I saw how much she liked me. Then after I gently massaged her whole upper body and torso for about 5 minutes... she kissed me... fu**.....
She immediately stopped and apologized but she still continued to lay in my arms. It was the most relaxing and comfortable thing and we just laid there for about an hour before we fell asleep.
Now... I literally have been thinking about her non-stop. We used to text each other once in a while but now I feel upset if a day goes by without talking to her. It rarely does though. So what does this mean? How should I handle this? How am I supposed to deal with the fact she has a boyfriend? Didn't she basically just cheat on him? I feel like **** because I basically told her I wanted her to do her thing and enjoy highschool but now that she has I can't deal with it. I think I love her and I've all but heard her say it so I know there's a strong connection here. Age difference really screwed this up but we're basically made for each other. Even all of friends say that if she wasn't dating anyone that we'd probably get married lol. But I can't even laugh because that's honestly where we eventually see this going.
I don't know if I want an answer or just a comment on the situation but can anyone throw me a bone?

She's turning 18 in may if that makes a difference

You have selected a girl who cheats on her boyfriend. She is still in high school. You are in college. What do you make of that? Ann

So you both have a thing for each other... She had the experience you wanted her to have- enjoy hs and not to miss out; like going to the prom with her current boyfriend. Now that she's finishing high school, it's okay for you let her have new experiences with YOU now!
However, you should discuss the situation about her current boyfriend. Something along the lines,
"Are you willing to break up with him?"
"Are you going to tell him that we had a 'moment'?" "Do you even feel bad for 'cheating' on him?"
"If your feelings are stronger for me, then I think you should end it with him"
"Do you WANT to be together?"
Her boyfriend could be a genuinely nice lad, after all- and if he is, then he deserves to find his 'love' and not be strung along as her pet.

You seem crazy for her and she seems crazy for you, fight for her! By now, her age shouldn't be an issue. I've got a few friend's with parents that have 10+ years age difference, and they're pretty happy couples.
Just keep in mind, she could be the type to develop crushes easily, and I wouldn't want you to get cheated on if you two decide to be together.
