When I was 12, I met this awesome girl (Karen). She was pretty, had very similar interests and liked talking to me. We were "friends" officially but I guess we both had a crush on each other. She moved away when I was 17, and with all the time wasted in school, we never really got a chance to talk properly in the last two years. She gave me a parting kiss, and left. I talked to her twice when I was 17-18, and then we both drifted apart.
I'm not what you would call an "introvert" or a shut-in, but a quiet person. I had a group of friends and many acquantainces during high school, but I'm the guy who initiates a conversation, gives his POV and then hangs in the background. I tend not to trust people easily, and follow a rather strict code.
I'm 18 and half now, and I'm in college (rather reluctantly, and I hate it). There's this girl (Lily) in my class who is STUNNING and seems to like me. She sat behind me on the first day, and a week later, she started talking to me, over rather mundane topics (like, she first initiated conversation by asking me why I was eating french fries in my dorm) (she followed me). It's been three months now, and we've spent quite a lot of time together. We meet almost daily, and she tells me about what she did yesterday. We're still "friends", and we haven't held hands or anything.
I was very depressed from 17-18 because Karen left, and I spent my last year of High School in a daze. I like Lily, but it feels wrong to be with her and to just let a better relationship with Karen go away. It's like I feel bad for letting Karen go while there's Lily here, whom I've known for just three months. What should I do?
1. Call Karen and talk to her.
2. Forget Karen.
If I call her, I might ever get in a rather loose relationship with her, but then I don't think a long-distance relationship would ever work between two people who haven't seen each other for almost two years. If this happens, then I lose Lily, who is much more immediate, and I fear I wouldn't be able to make it up to her (Lily) if I call Karen again.
What should I do, /adv/?
