Summarize this article in one sentence.
Don't break right out into the "I love you"s and don't talk about the future you want the two of you to have. You want to avoid speaking in definite terms about the future because this creates a lot of pressure and expectations for him...which is stressful and can scare him away! Instead, speak in terms of what you want to try or what you hope might become real eventually. "I hope we can try being more than friends,", etc. Don't be creepy when you tell him how you feel. This means no begging, no bargaining, and try not to touch him or get into his personal space until you know he feels the same way. You also shouldn't cling around him if he needs time to think about what you said. If you can, tell him how you feel in person. Using social media or a text can come across as not being very serious or, worse, being a joke. This is not how you want to start things with him. You don't want to rush into telling him and if he returns your feelings, don't rush into a serious relationship. If you're going to go through the torture of confessing, you want to be sure that you really like him first, right? This is can be a long process and one that will continue even if you start dating. Just focus on getting to know him for who he really is, by spending time with him and talking about things that are important to you: what you both want for the future, what your beliefs are, and what you like to do for fun.
Don't pressure him. Don't be creepy. Don't use social media or a phone. Don't rush into things.
