When you say I really like you then you are letting someone know that you care deeply, and that they mean a lot to you. Like and love are two different emotions, and you can really like someone without feeling any romantic attachment. I really like you quotes can be funny, serious, or even wacky at times. You may say I really like you to someone who has had a big impact on your life, such as your mentor or someone who possesses qualities that yo admire. When you like someone there is a possibility that this emotion can deepen into love over time but this does not have to happen. You should never say I really like you to someone just to hear them say it back though, always be honest about how you feel.
