I have a girl that is my classmate and she has a boyfriend in a far place. We are still both in high school. When I try to speak to her, my tongue seems to retreat so I cannot talk to her without a cause. I can only talk to her when others wants me to tell her something. We have been classmates for 3 years and we hardly have any conversations. She knows I like her but I always turn tail when I see her talking to the phone with her boyfriend. What should I do?

Just try to talk to her, that's all you really can do. But don't come across jealous, because that will definitely scare her away, as it will with any other girls. Just try to hang out after school, with Facebook and myspace and all these other networking sites it should make it easier to contact her, just don't come across as a stalker either. Try to find common interests... I like bowling if you like bowling or video games or stuff like that then it'd be good to talk to her and see if she likes the same things, try to plan a time to hangout outside of school, just as friends, but be careful not to come on too strong.

Aww.. thats really a badluck and many suffer from this jelous feeling... still it's a human nature
Well, according to me you should make her your friend on Facebook.. and if she comes online then u can easily chat for few minutes then hours..
In 2 to 3 days you can take her number, giving a reason that she is your friend and if u get absent then u can ask her over phone what was taught in class last day
When u get her number then.. find sm good proposal lines.. and message her
Write atlast that u just want to b her good friend..
Slowly and steadily u will get a chance to know her and she would know u too..
And if your luck will support u then she would surely fall for u.. provided u remain in a flirty nature with her..
