Do not be alarmed if they send you an email saying they like you. Simply respond with "I like you," but only if you do, or "Thanks, but we're just friends," and then wait for the next email. If you're getting emails from your crush within 3-5 minutes of sending them, they're hooked, so keep going.
You may tell your crush in person, text them, send them a card, or message them on social media.
How to Tell Someone You Like Them Without Telling Them You Like Them
You obviously want your crush to reply by telling you that they like you back, but this is not always the case. Don't put too much strain on the issue, and remind yourself not to put any pressure on this individual to reply by admitting they have feelings for you as well.
If they don't say anything within a reasonable time frame, it's probably best to move on with your life.
That being said, if you two end up dating each other (or even just being friends) you'll know what statement to make when the time comes. For now, enjoy the fact that they like you!
There's no need to put it off any longer. When you're alone and have made your crush feel at ease, just tell them how you feel. The sooner you start, the better, and the less likely you are to make yourself uneasy or ramble on about anything unrelated. Simply be straightforward and straightforward. Don't worry about coming across as cheesy or using words that aren't appropriate yet.
As long as you are both comfortable with where things stand, then there is nothing wrong with telling your crush directly how you feel. It's best to do so when there is nobody else around so that you don't appear desperate. However, if you catch them off guard, then they might not return your feelings right away. Give them time to process what you said before you ask them out again.
Give them a complement to make them feel good.
Everything you need to know to get your crush to like you back is right here.
