(back ground)
There's this girl that's 2 years older than me and I've liked her for half a year now. . I'm in grade 11 now and she's in first year university-she used to live across the street but she moved to another province,and last time I saw her was Christmas. I've known her for about 5 years but just started to have feelings for her when she was ready to leave... I try to talk to her online as much as possible and her mom thinks very highly of me.

On Christmas her mom came in while we were talking and started saying good things about the both of us. Her mom began to say "you know, she thinks that you-" then she jumped in and put her hand over her moms mouth and they started saying stuff in Chinese. Do you think she likes me? What should I say to her?

I'm going to be done high-school in around 13 months, and I'm ready to move to her city to go to her school if I can start a relationship- plus it's a good university. She's a really cool person, smart and beautiful, she laughs at my jokes and we can have fairly good conversations. I know lots of guys say that but I meant it, she's pursuing a medical career, as am I, and the more we talk the more I can't stop thinking about her.(I don't mean to arrogant) I also consider myself to be more mature than other kids my age-which distances me from my friends.

To add to that, her mom was talking about positive traits we had in common and was almost praising me and then her, slowly connecting us. She jumped in quickly like she knew what her mom was going to say, and that it was an embarrassing or personal secret.

As I'm reading your post, my first advice to you is: I wouldn't read too far into things. There are a lot of, "what if's." She jumped in and stopped her mom from saying something... that's all that happened. Just take things at face value for now, or you'll end up driving yourself crazy trying to unlock the drive behind every word she says and every action she does...

If you feel like you need to tell her how you feel, then just do it. You may feel nervous about telling her, but think about it- it's not that difficult. Be open and honest.
After that, it's time for her to say something or make a move.

As you sit there and think about the moment you tell her how you feel, what you'll say, what she'll say, how you're going to say it, and what her reaction will be... stop yourself and make sure you're not putting any expectations on what will happen, as far as her reaction goes. All you can do now, is say what you need to say, the rest is up to her.

K I think ill just go and tell her- my problem was the nervousness

Yeah, it's the only way to know for sure. Just man up and talk about it. Relationships take communication, may as well practice now, right? It's okay to be nervous, but it's not that difficult to just say something.

Before you plan your whole life around her, you better know, not hope, she feels the same as you, which I seriously doubt. (SORRY) You may be as mature as you want, but knowing what's on a woman's mind, and heart, is a task that takes a lot more than maturity my friend. It takes time to process the words and actions and we guys still get it wrong most times. Sorry, she comes off as a friendly big sister more than a love interest, despite what her mom says. Mothers are a poor barometer for a daughters feelings, and they are prejudiced.
