Whats my issue with girls?

Whenever a girl starts acting real nice to me I can't help but start to like her more than a friend and this has ended more than one friendship with me, and I feel like I come on too strong. For example, this girl I have only remotely known for like three years starts hanging out with me at the carnival, and she is really pretty, and nice to me so I have started to like her and it's been like 4 days since this happened and I think I have been A. wierding her out or B. annoying her. Can you give me insight and advice?

Sound like you're 14-15 years old. If so, that's normal. Young males often feel insecure about the opposite sex and try to prove themselves with every one that comes along. As you get older you will be more comfortable around them and with more experience, deal with it better.

You can probably save yourself some discomfort by waiting until you see signs that the girl you find attractive feels the same way. Make yourself more of a challenge, work on your self control and understand that romantic relationships are a bonding between TWO people. No matter how you feel, if you don't light her fire, it's not going anywhere.
