After you get an idea, do some research on his hobbies and learn as much as you can about them. This way, you'll have plenty to talk about.

Dress cute around him. This may seem counterproductive but you have to think about how a man's mind works. Many girls miss the mark by dressing sloppy trying be "one of the boys." Obviously you can't dress sexy at first, because his thoughts will go way beyond what you want at the moment. If you dress too down though, like in ratty sweats and a stained T-shirt, the man may not want to hang out with you at all. No matter what, you are female and you should dress accordingly. If you stick to somewhere in the middle, like jeans and a cute T-shirt that's attractive without giving him too many ideas, he's more likely to want to see more of you and be seen with you.

Talk like a guy. Do not cut yourself down or any other women down in front of him. When you do it to yourself, he'll get the picture of a girlfriend asking "Do I look fat in this?" If you are catty about another woman that is around, he'll have that same girlfriend image in his head of you being jealous. To truly be successful about how to make a guy your best friend; you need to find physical attributes that you admire about other women when you're hanging out together.

Nurture him. Believe it or not, one of the reasons that guys pick girls to be their best friends is because of their softer side. A man likes to vent too and sometimes it is just harder to share his emotions with his male buddies. He might want a female's perspective on certain situations sometimes, without the risk of feeling like he's embarrassing himself in front of a romantic girlfriend.

Keep his secrets. If he does embarrass himself in front of you or tells you something really juicy, keep it to yourself. Do not share it with anyone, including your closest girl friend. The greatest trick about learning how to make a guy your best friend is to show him that he can be himself around you without reprimand or consequence.
