Summarize this article in one sentence.
After a safe amount of time spent in this intermediate zone, you can proceed to the next step. This amount of time will vary depending on the guy: you'll have to feel when it's safe to move on. Basically, you'll know you can go on when he starts giving you some extra attention too. Now, it's time to enter the very-near-to-flirt zone. Tell him things like "I miss/missed you," "I saw/made/met... and I thought of you." Lean on his shoulder if you're tired, for example. At this point, you must have reached a level of confidence between you and him where it's possible for you to do such a thing. Physical intimacy is essential: it will allow him to start questioning his feelings. But don't go overboard; at this point, he's still only your friend. Physical contact must therefore be occasional. Always have a plausible reason: tiredness, feeling blue, or needing a hug. Once again, it is essential not to scare him. Never make it absolutely clear that he is the one you want. Guys like to fight for what they want. So, make him chase you a little bit. Let him know that you're interested, but don't be so available that he thinks you have nothing better to do. Don't respond to his texts immediately. Don't answer the phone every time he calls. Don't be available every time he asks you out. Ignore him only a few times; the risks are if you ignore him too much, there will be trouble coming in the long run. The up side is his heart will be questioning whether you like him or not. Don't seem available all the time after you've gone past your "friend stage." This will make him miss you and wonder what is going on in your life. He will know he's not the only subject on your schedule, leading him to care and love you more and more. Perhaps he'll do it himself in that case, congratulations but perhaps he won't. In that case, don't panic. Remember it's just as hard for boys as it is for girls. If he doesn't ask you out, it doesn't mean he doesn't like you. It might mean he's scared. Drop hints like "I'd love to see this movie but, alas, all my friends have seen it already." And if he still doesn't ask you out, well... do it yourself. Gender roles are so last century.
Make it more obvious. Touch him more. Leave him wanting more. Ask him out.
