A girl wants nothing more than someone who she can depend on. Be there when she is upset, or when she might just need someone to talk to. Both of these things will show her that you care.
Don’t be the type of person who appears to like her, and then completely ignores her for the next three days or flirts with another girl across the room. This will make her think that one girl isn’t enough for you, and if she likes you back, this will hurt her, which is the last thing you want to do.
If she tells you something personal, such as an event that went on at home or possibly an argument she had with her best friend, it means she trusts you. If she trusts you, she is counting on you not to go and tell all of your friends about her problems, so don’t! You’ll just lose her respect and will lessen your chances of being with her.
The more you two have in common (like if you guys both think loyalty is important and both listen to the same music genre), the more likely she will want to talk to you and spend more time with you.
Don’t change your interests or the music on your iPod just so that you guys will have something in common. If you guys don’t, don’t force it. You might just not be compatible.
Find a quiet space where you two can be alone. Tell her how you feel and don’t look away from her when you do. Do NOT tell her over I.M. or text message – it’s easier to reject someone over text message than it is face to face and it will show her that you aren’t afraid of conversation. Allow her tell you how she feels, and if things take a turn for the worse, don’t panic. Tell her that you’d still like to remain friends and give her a hug.
